Nobody is beating that drum because it comes off as religious crazy-talk. I see zero reason why it should be our purpose to create any kind of metaphorical species-offspring, especially when you yourself say that any concept of making it safe for us to share a planet with is oxymoronic. That sounds like saying, "our purpose is to build an apocalypse and die for its greater glory". Again, that comes off as religious crazy-talk of the suicidal kind.
It seems to me there are entirely sane reasons to work on advanced machine learning and increasingly general AI. That's just not at all one of them.
Well nothing, we get to determine it. According to what you write, your assumption is that the "grand goal" is to "enjoy life."
I say, that's probably not it - or rather I don't think so (based on my experience/research, general revealed preferences for humans writ large).
So my proposition is that our "grand goal" should be to build AGI.
Such a narrow view of life is a tragic waste, regardless of what you think that destiny is. I expressed my frustration with the narrowness of your perspective in a metaphorical way. I am not literally assuming that you don't go outside.
But you pretty much have to believe the first (our intelligence is just neurons, there is no magic behind the curtain) in order to believe in AGI at all.
Right now, Humanity has no "goal" as it is currently with AGI - we haven't figured out a seed goal for AGI yet. In my view we should agree that the meaning for humanity is to create our successor: AGI. This fits into the evolution progression, only it becomes self directed.
Numenta, OpenCog et al... all of their founders want to create AGI, but they aren't evangelical - they are focused on creating companies which can move progress forward on NAI. Which by the way makes perfect sense, that's exactly what I do because it's impossible to fund AGI for it's own sake. In fact I NEVER talk to investors about how our goal is in the AGI space. For a million different reasons.
Seems like it's a space where you can pitch yourself as "AGI", but you have to get your revenue from solving real-world machine learning problems.
In fact it's worse. If you pitch yourself as AGI you'll get 99% of investors to walk away immediately.
No what I am saying we are not hearing is this:
"The purpose of humanity is to build an Artificial General Intelligence, it's the thing that we should all dedicate our lives to because it's the offspring of humanity and the most important thing any of us will ever contribute to."
Nobody is out there beating that drum yet, and it's a shame.
