>But I'd say planes are more like "narrow AI", and we already have that.
Not sure I buy the analogy. A plane is already more like an AGI, you have to figure out enough aerodynamics to get the thing to be airworthy, enough materials science to develop the proper materials to build it, enough mechanical engineering to get the thing to be maneuverable, enough Software to make it all work together etc. So it's already an amalgam of many other types of systems. A Hang Glider might be more akin to a Narrow AI in this framework.
>I'd consider the possibility that we WILL get AGI in 10, 30 or 100 years, but it won't be that impactful compared to the narrow AIs already running everything!
I think this is misunderstanding what an AGI really represents. Imagine John Neumann compared to a Chimpanzee. There's no comparison right, the chimp can't even begin to understand the simplest plans or motivations Von Neumann has, now imagine an AGI is to Von Neumann as Von Neumann is to the Chimp, only the metaphor doesn't even work because there's no reason the AGI can't scale further until we're talking about something relative to us as we are relative to Ants or Bacteria. If you think nothing will change when a system like that exists then I don't know what to tell you.
>I'd consider the possibility that we WILL get AGI in 10, 30 or 100 years, but it won't be that impactful compared to the narrow AIs already running everything! It will be slow and suffer from Moravec's paradox (i.e. being much less efficient than a human, for a very long time)
If one considers the above and is comfortable with the idea that such a thing might be possible in our or our children's lifetimes then we should be doing everything in our powers to solve the alignment problem which is extremely non trivial and enormously consequential. At minimum an AGI could direct, orchestrate or improve the Narrow AI's in ways that no Human could hope to understand. All bets are off at that point.
I think the paradox was more poignant in robotics, but in any case recent advances have put tasks like object recognition, real world path planning, logical reasoning, etc well past human child levels and at or beyond adult levels in some cases.
>Now even Musk admits that, after Gary Marcus and others were telling him that since 2015.
Marcus is a constant goalpost mover and he'll be shouting about AGI's not really understanding the world while he's being disassembled by nanobots.
