Of course, there are debates around which inventions count as significant. And there is recency bias.
Never underestimate the power in something easy to communicate.
Yes, I suppose that's the biggest thing with these "futurologists": their predictions are both tantalizing and easy to digest. I reserve the right to remain skeptical about any of these Silicon Valley religions though.
What strikes me as particularly interesting about Silicon Valley and some techie circles -- as opposed to Nostradamus -- is that many of these people self-identify as hiperrational, agnostic, atheist or wary of traditional religions, yet here they are, building their own religions under a more palatable technological guise (I could list ideas like the Singularity, Super AI good or bad, immortality, "we're living in a simulation", "every problem in the world can be fixed with the right app", etc, but if the list of absurdities goes long enough I'm sure to hit some raw nerve, so I'll stop here).
These modern day Nostradamuses also tend to overinflate their own importance in the wider world. Outside of techie circles Kurzweil is a nobody, and the notion that his theories are some bar that other theories must somehow pass is laughable.
He claims he's right even when he's obviously wrong. He is not someone whose predictions should be blindly trusted.
Likewise, if someone said "human aging and death are unavoidable" this wouldn't be bold just because Kurzweil has written a lot about immortality.
A lot of work is being done to make bio-silicon fusion real, with use cases like creating olfactory sensors.
And our increasing control over both brain and genes may be the pathway to more general biological computation.
It seems like the whole analysis is predicated on the idea that technology = software made in Silicon Valley, with unimportant secondary factors. That 3M and ExxonMobil are not "tech" companies because they don't make iPhone apps.
Every company is a tech company, not because we've had computers for a while, but because technology is what we build to get what we want.
These kinds of narrow, myopic, siloed takes miss the forest for the trees.
If you think the epitome of human evolution is going to be people looking at bright rectangles for eternity, you haven't been paying attention to what technologists are doing.
