And most of that is then stuff you can throw away because it's not pre-training your brain; and the stuff that does, while we don't know the full mechanism, we know it works through the laws of physics.
Knowing the weights without knowing the full graph of the model they're used in, just the endpoints.
There's a lot of valid stuff in what you say, I am aware I'm glossing over a lot of challenges to get a copy of a human — to what extent is e.g. the microbiome even contributing to our intelligence, vs. being several hundred different parasites that share a lot of DNA with each other and which happen to accidentally also sometimes give us useful extras? It's hard work telling which is which — but my claim is that the nature and scope of such work itself still allows us to say, as per one of the parent comments:
> I think it's important to remember that we know neural networks can be trained to a very useful state from scratch for 24 GJ: This is 25 W for 30 years (or 7000 kWh, or a good half ton of diesel fuel), which is what a human brain consumes until adulthood.
If this were a 100m sprint, then I would agree with you essentially saying that we don't even know which country the starting blocks are in, but I am still saying that despite that we know the destination can be reached from the starting blocks in 10 seconds.
