Empirically, we likewise don’t seem to be living in the world where the whole software industry is suddenly 5-10 times more productive. It’ll have been the case for 1-2 years now, and I, at least, have felt approximately zero impact. I don’t see 5-10x more useful features in the software I use, or 5-10x more software that’s useful to me, or that the software I’m using is suddenly working 5-10x better, etc.
Diminishing returns! Scaling laws! One concrete version of “5x productivity” is “as much productivity as 5 copies of me in parallel”, and we know that usually 5x-ing most inputs, like training compute and data, # of employees, etc, more often scales logarithmically instead of linearly
The fact that they have a short lifecycle with only 1 lifetime breeding cycle is though. A lot of intelligent animals, like humans, chimps, elephants, dolphins, orcas, have long lives with many breeding cycles and grandparent roles. Ideally we want an animal that starts breeding in 1 year AND lives for 5+ breeding cycles to be able to learn enough to be useful over its lifetime. It takes so long for humans to learn enough to be useful!
