Human knowhow is rich, but fundamentally contained in one mind.
The only way to transmit a thought flower from one mind to another is to do an insanely lossy and expensive distillation into a seed of insight, to then be shot into another mind via a stream of words, where hopefully they blossom into something vaguely like the original flower.
This transmission bottleneck is a fundamental characteristic of what it means to be human.
It means that knowhow cannot compound, except in emergent structures like corporations.
Knowhow is fundamentally limited to what a single human mind can contain, and when they leave this earth it's gone, with only the distilled fossils of it left behind in words.
LLMs don't have this restriction.
The knowhow can be transmitted, at full fidelity, indefinitely, because it is just data.
Knowhow one model absorbs can directly seed the knowhow of future models.
