But hubris - yes it is hubris. Because there is no scientific basis for the assertion that we will cross that chasm into 'true' AI, and thus it's based just as much on faith as any religious belief. And it's hubris because they claim a scientific basis where there is none.
When there is a scientific basis or proof that we've reached (or will reach) this 'singularity', you won't see me complaining. I'm not anti-science. I just don't think it's ever going to happen.
On a semi-related note, doesn't anyone find it kind of odd that Ray Kurzweil's calculations for when the singularity will occur happen to be just about the time his natural life will end (statistically speaking)? These projections are all driven by ego and faith, very little by science...
About religion and science; it is about definition where there difference is; IF you accept some definition X as being strong AI then when we reach that we have a scientific reality. The chasm and 'true' AI and what these are in scientific terms are vague, however in science we accept definitions of how nature works and if those definitions are things you hold true there is no reason why it won't be reached as there is not 'special' in the fabric of our brains which we couldn't copy given advanced enough ehm, take your pick; biology, nanotech, electronics, 3d printing etc. If you however cannot agree on definitions and have that (to me alien) quality of accepting mystery above all, then sure it's all believe or not. Not a good conversation maker as we are done after 2s, but he.
