Like attempting to do a PR campaign for a non-profit via Wikipedia by piggybacking onto a Hollywood big-budget movie..?
I do consider the effect of shifting public perception on an existential risk issue by a tiny bit to be worth lives. UFAI is on the road to killing people. I do think you engage into failing to multiply if you think that isn't worth lifes.
It looks as if you're assuming that the overall PR effect of having MIRI or MIRI supporters add links from the Wikipedia article about Transcendence to comments from MIRI would be positive, or at least that it's more likely to be positive than negative.
I don't think that is a safe assumption.
As David says, one quite likely outcome is that a bunch of people start to see MIRI as spammers and their overall influence is less rather than more.
There's a big Hollywood movie coming out with an apocalyptic Singularity-like story, called Transcendence. (IMDB, Wiki, official site) With an A-list cast and big budget, I contend this movie is the front-runner to be 2014's most significant influence on discussions of superintelligence outside specialist circles. Anyone hoping to influence those discussions should start preparing some talking points.
I don't see anybody here agree with me on this. The movie has been briefly discussed on LW when it was first announced in March 2013, but since then, only the trailer (out since December) has been mentioned. MIRI hasn't published a word about it. This amazes me. We have three months till millions of people who never considered superintelligence are going to start thinking about it - is nobody bothering to craft a response to the movie yet? Shouldn't there be something that lazy journalists, given the job to write about this movie, can find?
Because if there isn't, they'll dismiss the danger of AI like Erik Sofge already did in an early piece about the movie for Popular Science, and nudge their readers to do so too. And that'd be a shame, wouldn't it?
