I've always thought it's never too early to start allocating significant resources to AGI research and safety given the potential impact. That said, I've up until very recently agreed with your take on the situation.
What changed my mind was an article detailing the latest advances in silver nanowire mesh networks.[0]
I knew neural computing was a thing, but not that we already had a computing substrate capable of self-organizing its own neural architecture based entirely on external input, with power requirements analogous to the human brain. No firmware or software required.
One could say that human physiology remains far more complex just on the substrate front alone, what with the brain being an incredibly complex, delicate balance of chemicals and heterogeneous cells. However, this particular artificial substrate is already succeeding in basic learning tasks, despite the fact it's far simpler.
I steongly suspect we've figured out at least one artificial computing substrate not only capable of, but perhaps well-suited towards producing AGI, and that it's just a matter of scaling it.
Of course, once you scale the technology sufficiently, the question then becomes how to architect and train it into an AGI. You say as much above, but I suspect the architecture need not be human to be a threat, or to otherwise become extremely powerful.

- mrfusion 9y agoThanks for pointing me to that. Very fascinating! I’m wondering if it’s possible to code a simulation of what these wires are doing? Since most of us don’t have access to the nanoscale silver contraption we could still be studying the operation.
- phs318u 9y agoFascinating! > the question then becomes how to architect and train it into an AGI. If that’s the question then why even bother with silver nanowire “brains”? Why not just grow a human brain out of some suitable stem cells and work with that? Leaving aside the massive creepiness factor.
- rl3 9y agoI'm guessing the answer is a combination of synaptic latency and ethics. The human brain's latency is relatively slow relative to traditional computing. The brain's synaptic latency is measured on the order of milliseconds, while a modern IC's latency might be measured on the order of nanoseconds or even picoseconds. As messed up as it is, using biology as you describe might actually be safer once we get close to AGI, even if it is creepy as hell. There's something to be said for having a machine that's physically limited to thinking as fast as a human can (even if it is vastly smarter), versus one that can figure out a new branch of physics in the time it takes to blink.
