Google’s Vint Cerf avoiding responsibility

Yesterday morning I was on my way into Lancaster and listening to the Today programme. Google’s ‘internet evangelist’ Vint Cerf was being interviewed by John Humphrys and the topic was ‘should the internet be regulated like other media’.1

Not surprisingly Vint Cerf thought not, but I was surprised how well he avoided actually saying so. John Humphrys is experienced and politicians fear him in these early morning interviews, but to be honest he was completely outclassed by Vint Cerf who sidestepped, avoided and generally never addressed the question.

Web 2.0 was the heart of the issue. With end-user content now dominating the internet do service providers such as YouTube (of course owned by Google) have any responsibility for the kinds of material hosted?

This was in the context of videos of ‘happy slappers’ and other violent attacks being posted, but more generally that whereas TV in many countries is limited in the kinds of material it can show, particularly early in the evening when children are more likely to be watching, is limited by a mixture of voluntary and satutory codes. Why not the internet?

Vint Cerf repeatedly re-iterated the same message “Google is law abiding” if content is not legal it is removed. Implicitly the message was “if it is not illegal it is OK”, but as I said he carefully avoided saying so.

The closest point to actually addressing the question was when John Humphrys suggested that technologies could be misused like research for atomic power being used for nuclear weapons (strange I thought it went the other way round?). Vent Cerf’s response was, the standard neutrality of technology stance, that the makers of roads were not responsible for car deaths, strip development … the same argument used by arms dealers, manufacturers of gas guzzling cars, and scientists in every repressive regime in recent history.

According to Cerf if you are a worried parent you need to buy good filtering software; the solution is at the edges of the net … and of course does not involve the likes of Google … who it appears from the context is at the centre?
Now there are very good arguments against regulation both ethical (freedom of expression) and practical (volume of material, international access). The disappointing, and worrying, aspect of this interview was that Google’s key public face was unwilling or unable to constructively enter the debate at all.

in the news – second chances for killers and students

As well as Hurricane Dean which has been dominating much of the news, two items have caught my attention over recent days. One is the debate surrounding the court decision preventing the deportation of Learco Chindamo, the killer of school teacher Philip Lawrence 12 years ago. The other is the release of statistics showing drop-out rates from UK Universities.

Learco Chindamo came to the UK when he was 5, killed Philip Lawrence when he was 15 and has been in prison since. His life sentence carried a minimum term of 12 years and next year he will be eligible for parole. He is also a Filipino by birth and has an Italian passport, so the Home Office intended to deport him on his release, but were prevented by the courts.

Philip Lawrence was a Head Master who died protecting one of his pupils. His wife and family have had to live with that ever since. Furthermore, she had been promised by officials that he would be deported.

The case is distressing and traumatic, but in the end clear. The mark of a civilised society is surely how we treat the undeserving. This is not a man who came to the UK to work and then murdered, but someone who has spent all his childhood here, albeit under the influence of London youth gang culture, and who knows no other country. Deportation would not be sending back but throwing away, like those sent to Australia in the past.

If this has not been such a public case, we might have never have heard of this decision. And because it is public we have some inkling of the anguish we might feel if it were our family not some other. But the purpose of law is precisely to protect us from the retribution we would want if we know the victim and balance that with the mercy we would seek if we knew the criminal.

We might ask questions about our criminal justice system. Is twelve years enough for a cold blooded killing, even if the killer is 15 years old? Is 15 a child or a man? Do we trust the parole system to only release him if it is safe to do so? These questions seem valid no matter the passport a man carries, and it is right to debate them. But to deport a man, who has served half his life in jail, to a country he has never known would have been simply wrong.

It seems frivolous to move from this to university drop out rates, but they are not so far distant.

In some universities the rate is nearly 20% compared to near 2% for the ‘best’. In the TV report other figures were quoted … and certainly the 20% figure at one point sounded as if it were the national average rather than the average at the ‘worst’ institution.

The TV report also noted that those with worst drop out rates were largely ‘new universities’1 and the Vice-Chancellor of Liverpool Hope was interviewed and staunchly defended his own institutions policies to inform students about the nature of courses.

What was left unsaid was that these institutions mainly take those with the lowest academic achievement at entry.2 In other words these serve the ‘lowest’ in society and, as I am sure in other countries also, this is as much determined by social situation as academic ability.

There is often debate about the university system and whether these are ‘real universities’. I have written about this before when I was education columnist for SIGCHI Bulletin: I had recently returned from a visit to South Africa and read on my return a particularly scathing attack in The Times on new university courses. 3 Recently this has been in the media again when “The Taxpayers Alliance’ (I assume representing everyone except children, the elderly and the poor) issued a “non-courses report“, damning degrees such as “Equestrian Psychology” and “Golf Management”.

Now we might debate the academic merit of particular courses (although strangely the ones cited by the TPA sound more academic than many … perhaps reflecting their own understanding of academic content?) … and I stand on shaky ground as my own discipline of computer science, would have been in a similar position 40 years ago. Also it is certainly true, although it is politically incorrect to say, that academic degree classifications at different institutions are not worth the same and indeed, although even more politically incorrect, classifications now at the ‘old universities’ are not the same as they were 15 years ago. We can also ask whether the move to push more and more post-18 education into universities, or whether the changes in that education are in the right directions.

However, notwithstanding all this, it is the new universities that have borne the brunt of the expansion of higher education in the UK and not surprisingly have the most difficult job to do. They take students who at 18 have the lowest A Level grades and, even taking into account the different meaning of classifications, take many of those students to a high level of academic achievement.

These are students who would not have had that chance when I was 18.

Not surprisingly some find that it is not for them, but the 20% drop out rate at the ‘worst’ institutions should be seen against the 80% of students at these institutions who are succeeding, but would never have been given the chance in the past.

Whether even the 20% of drop outs can be seen as a sign of failure, depends on whether they see themselves as having ‘failed’ or having learnt where their true abilities and interests lie. My guess is that for many it will be the former and this is the issue to tackle: how we can have an education system that is about allowing people to develop and learn their strengths not simply learn what they cannot do?4

And what of those 80% who have been given a chance they might not have had. Is it right to say that a person has no more to learn and be judged for life by what they achieve at 18 years old? And is it right to say that a man cannot change and be judged for life by what he did or was at 15 years old, 26 or even 47?

  2. I am carefully choosing words here as achievement at 18 years may not be a good measure of initial promise, current ability or future potential. [back]

Single-track minds – centralised thinking and the evidence of bad models

Another post related to Clark’s “Being there” (see previous post on this). The central thesis of Clark’s book is that we should look at people as reactive creatures acting in the environment, not as disembodied minds acting on it. I agree wholeheartedly with this non-dualist view of mind/body, but every so often Clark’s enthusiasm leads a little too far – but then this forces reflection on just what is too far.

In this case the issue is the distributed nature of cognition within the brain and the inadequacy of central executive models. In support of this, Clark (p.39) cites Mitchel Resnick at length and I’ll reproduce the quote:

“people tend to look for the cause, the reason, the driving force, the deciding factor. When people observe patterns and structures in the world (for example, the flocking patterns of birds or foraging patterns of ants), they often assume centralized causes where none exist. And when people try to create patterns or structure in the world (for example, new organizations or new machines), they often impose centralized control where none is needed.” (Resnick 1994, p.124)1

The take home message is that we tend to think in terms of centralised causes, but the world is not like that. Therefore:

(i) the way we normally think is wrong

(ii) in particular we should expect non-centralised understanding of cognition

However, if our normal ways of thinking are so bad, why is it that we have survived as a species so long? The very fact that we have this tendency to think and design in terms of centralised causes, even when it is a poor model of the world, suggests some advantage to this way of thinking.

visualising vocabulary

Fiona just pointed me to Visuwords a lovely visualisation of word association using WordNet data. The image below is of the word ‘human’ and you can see two clusters one corresponding to the noun human and one to the adjective meaning humane/caring

Visuwords is Flash front-end and PHP backend. It appears to use some variant of spring and ball visualisation. You can download the source … so could use it as the basis of visualisation for other kinds of data such as web sites.

multiple representations – many chairs in the mind

I have just started reading Andy Clark’s “Being There”1 (maybe more on that later), but early on he reflects on the MIT COG project, which is a human-like robot torso with decentralised computation – coherent action emerging through interactions not central control.

This reminded me of results of brain scans (sadly, I can’t recall the source), which showed that the areas in the brain where you store concepts like ‘chair’ are different from those where you store the sound of the word – and also I’m sure the spelling of it also.

This makes sense of the “tip of the tongue” phenomenon, you know that there is a word for something, but can’t find the exact word. Even more remarkable is that of you know words in different languages you can know this separately for each language.

So, musing on this, there seem to be very good reasons why, even within our own mind, we hold multiple representations for the “same” thing, such as chair, which are connected, but loosely coupled.

I was just sent a link to an article in The Psychologist “Sleep on a Problem… It works like a dream” by Josephine Ross

The article gathers loads of anecdotal evidence of creativity in dreams … including, inevitably, those benzine rings!

Personally … while I’m sure that some things happen unconsciously and during sleep, my guess is that 90% of these creativity stories have simpler reasons through selective memory or semi-random inspiration.

tagging … I am not alone … or am I?

I’ve noticed that I reuse very few tags … and thought I was just a poor tag-user. However, I read the other day a reference to a paper at the CSCW confernce last year; it reported that the average number of re-uses of a tag was just 1.311 . I thought this meant that most tags are never reused … I am not alone 🙂

Having downloaded and read the paper it turns out that this is the average number of users who use a tag – that is most tags are used by only one person, in fact individuals reuse their own tags a lot more … so I am no-good tagger after all 🙁

Incidentally, I use ultimate tag warrior plugin for wordpress and it seems OK. Only drawback is that if you want tags displayed with your post, they really get inserted into the post itself. This is not a problem for tags at the end, but would mess up an RSS feed if you like your tags above the post. I guess this is because wordpress does not have a handle for plugins to add things to display loops, so the only way to ensure the tags are displayed are to make them part of the post.

Also Nad sent me a link to a neat tag visualisation by Moritz Stefaner.

digital culture

I was at futuresonic last Friday doing a panel keynote at the Social Technologies Summit. I talked about various things connected to imagination: bad ideas, regret modelling and firefly/fairylights technology. On the same panel was a guy from Satchi and Satchi who created television adds for T-mobile and a lady from Goldsmiths who described a project for Intel where they studied a London bus route. The chair Eric introduced the session with a little about blogging and other web-based technologies and in general we were immersed in the ways in which digital culture pervades the day to day world.
In my way home on the train I sat opposite a father and son who were playing hangman. The boy was about 6 or 7 and the father had to help him and sometimes correct him. Every so often I noticed the words they chose, but just before I got off the train there was obviously the father’s hardest challenge yet. I gradually noticed the hightened excitement in the voices … it was a word with ‘X’ and ‘Y’ in it.

As I stood to get up, the boy eventually got the last letters and completed the word …

omnignorance, the future of the web

The dream of the web seems a form of omniscience, unlmited and universal knowledge available at the vlick ofof a button or least at the click of a Google ‘Seach’ button. However, last night I was on a site that empitomised the problems of the web.

I was pointed to a blog entry about a presentation that the blog said was “Simply the best presentation I’VE EVER SEEN!“. I was intrigued and and followed this to the Identity2.0 site and in particular a page about a keynote at OSCON 2005.

The entry about the talk mentioned ‘Identity2.0’ and ‘digital identity’ so guessed this was something to do with single logins (like MS passport) or open authentication, which has long been an open issue (with many ‘solutions’ but so far little success). However, was this person and this site talking about one of these such as plain open authentication, or something deeper.

Well it is fine for the page about the talk not to say clearly, it is written within the context of the Indetity2.0 site, so I looked for an ‘about’ link or something like that … nothing I stripped the url back to plain identity2.0.com and of course simply got to a stabdard blog front page (I guess rather like this one), with the latest news, but nothing to gove over context or background.

In fact by chasing yet more links to other sites, by half guessing from various abstracts, blog entries, etc. I managed to pick out half a story about what this was about … but why so hard?

This reminds me of the problem I recorded a month or so back when trying to find last week’s (as opposed to yesterday’s) news. Really easy to find the latest item or even the hotest item, but really bad at getting to the background that gives context and turns buzz words into meaning.

At the risk of sounding like a codger at a cafe table, the same is true of much software documentation. If you have seen the software grow and develop over the years it makes sense, but to students trying to make sense of Java packages, AJAX, Mac/Windows APIs, it is like fumbling in the dark. Good signpoosting at every street corner, but no roadmaps.

In all these cases there are real questions we want to ask, this is not like meandering around Flickr or YouTube, travelling just for the journey. However definitive statements (I’ll not say answers) give way to half-overheard conversations in a coffee shop.

It is often said that experts know more and more about less and less untul eventually they know everything about nothing. It seems we are turning into a generation who know less and less about more and more until we know nothing about everthing – omingnorance rules.
