Correction:

"Any time we're impressed by what non-human animals do, it's simply because we forget that they have genetically inherited sophisticated knowledge, which was created by biological evolution, not by those animals."

@dchackethal · · Show · Open on Twitter

Common error: mistaking the sophistication of an animal's knowledge with the animal being intelligent.

For the former, the animal need only contain sophisticated knowledge—never mind where that knowledge came from—for the latter, it must have created the knowledge itself. twitter.com/neiltyson/stat…

From here, it's just one more step to meeting a necessary condition for AGI: making it possible for the program to correct its own errors.

@dchackethal · · Show · Open on Twitter

Applied to programming, it means we shouldn't judge a program by how well it solves a given problem, but by how easy it makes it to detect and correct errors it already contains.

Similarly, in science, we do not judge institutions by how much they produce or entrench good theories, but by how easy they make it to criticize and replace bad theories (ibid).

No, there is no purpose in the evolution of ideas. Ideas get themselves adopted because they’re good at spreading. Some ideas help improve world views and intellectual developments etc, but some don’t.

Plus memes evolve too quickly to evolve genetic defenses against them. Not to mention that even if it were possible, memes are much more powerful than genes and easily override genetic instructions (as evidenced by the religiously-spread meme of celibacy).

Also, following Dawkins, I believe memetic and genetic evolution are largely separate. But even if they weren't, parasitic genes and memes can manage to spread well despite hurting their hosts by keeping them alive well enough to spread, but without promoting their wellbeing.

  1. I think AGI will be achieved in a qualitative jump from something much less powerful, but it will take time to get to that jump.

By basing investment decisions off of skin color, you’re lowering the standards for blacks relative to nonblacks, which is economically counterproductive, patronizing, and, of course, racist.

You’re clearly making investment decisions based on race—otherwise you couldn’t account for your “subconscious bias,” which is a non-falsifiable idea that people can always use to justify decisions based on skin color.

@shl

(And btw, by admitting to “subconscious bias” you basically admitted to harboring racist thoughts against black people.) So then, the question is, how can you ensure a “fair” outcome without favoring black people and disfavoring white people?

I take that as a “yes,” because, to ensure you’re not “exhibit[ing] any subconscious bias,” you must look at the ratio of black founders you invested in. That’s why you share the number of “black investments” so proudly.

Most of the anti-AGI worries translate into this: sentencing AGIs to death for crimes against humanity they didn’t commit, nor could have committed because they haven’t been born yet, but might possibly commit.

Yes, an AGI is literally a child. It will have a few inborn ideas and needs to figure out everything else for itself. Learn to perceive, learn to communicate, learn to move, etc.

How quickly that happens depends entirely on the child, just like with human children.
