I suspect the root cause is that it's harder and scarier to imagine good outcomes. It exposes us to disappointment, and when you do it publicly, it looks "crazy".
Another explanation is that there's no direct consumer for "more." Individuals, corporations and states are not in themselves interested in "a larger amount of science," or anything analogous, despite the fact that they would all benefit ambiently.
The net effect is that it's only "safe" to claim reduced risk (i.e. lower costs).
From my perspective, we are desperately short of scientists, researchers and engineers, but we are using an outdated economic model to leverage their findings. LLM’s are a large part of Bush’s Memex and Jobs’ bicycle for the mind visions for intelligence amplification, and in some ways exceed them. I hope we trampoline from how we currently use basic seeking efforts for knowledge.
Or that the floor is raised, at least, and AI empowers average scientists to do substantial work.
A large amount of people building their own customized apps for themselves.
Similarily, everyone becoming their own accountant / lawyer / other professional services.
These professional services will defend themselves with gatekeeping. Suddenly it doesn't depend anymore on the quality of your legal advice, but whether it has been stamped by a qualified Lawyer. It doesn't matter that your taxes are correct, but whether they are submitted by an approved accountant. Etc.
So it does not follow that companies can bank the savings from firing people. Anything AI can do for me it can do for my competition as well, and humans still make the difference. The big question in the AI age is "why pick me?" why hire me, why invest in my company, why buy my product, in a sea of similar products made by everyone. A differentiation crisis accentuated by AI.
You can of course have many independent small groups, but this is trivial and best left unsaid in the context of this comparison.
It's not as if there is a limited amount of R&D to do.
