Given his previous poorly written "Trouble with CEV" ramblings, this is a pretty decent talk. Of course, his example of counterfactual reasoning only works when most people do not use it (the assumption was that someone else almost as good, would become a doctor instead, which breaks down if everyone thinks this way and chooses a different career path). This is like applying counter-factual reasoning to voting and staying home, which results in dismal participation rates.
My prediction is that it is unlikely that a majority of people will use counterfactual reasoning in relevant decisions before a singularity or human extinction.
Even if a majority did it, it would still be profitable to have an even larger majority using it. So I wouldn't worry about the issue of others doing the same. In the same way I don't worry about everyone going to the same movie I decided to watch.
I still think though that the same format of argument should be valid for making a positive commentary on it. If the Less Wrong crowd doesn't do so, who...
Diego Caleiro, a past SI visiting fellow and current leader of a transhumanist institution in Brazil, recently delivered this TED@SaoPaulo talk on Friendly AI and Effective Altruism. If it goes viral, it has a chance to be selected for TED Global. (The importance thing is to have lots of positive comments on the TED page, methinks.) TED Global's talks reach on average 40,000 viewers within the first 24 hours, and 500,000 within half a year.
