Vincent Müller and Nick Bostrom have just released a paper surveying the results of a poll of experts about future progress in artificial intelligence. The authors have also put up a companion site where visitors can take the poll and see the raw data. I just checked the site and so far only one individual has submitted a response. This provides an opportunity for testing the views of LW members against those of experts. So if you are willing to complete the questionnaire, please do so before reading the paper. (I have abstained from providing a link to the pdf to create a trivial inconvenience for those who cannot resist temptaion. Once you take the poll, you can easily find the paper by conducting a Google search with the keywords: bostrom muller future progress artificial intelligence.)
In the paper human-level AI was defined as follows:
Given that definition it doesn't seem too surprising to me. I guess I have been less skeptical about this than you...
What sounds crankish is not that a human level AI might reach a superhuman level within 2 years, but the following. In Yudkowsky's own words (emphasis mine):
These kind of very extreme views are what I have a real problem with. And just to substantiate "extreme views", here is Luke Muehlhauser:
The two quotes you gave say two pretty different things. What Yudkowsky said about the time-scale of self improvement being weeks or hours, is controversial. FWIW, I think he's probably right, but I wouldn't be shocked if it turned out otherwise.
What Luke said was about what happens when an already-superhuman AI gets an Internet connection. This should not be controversial at all. This is merely claiming that a "superhuman machine" is capable of doing something that regular humans already do on a fairly routine basis. The opposite claim - that th... (read more)
