Yours in that from it follows, that there's still quite a bit of room to get ahead of OpenAI for smaller players.
Parent's in that in order to achieve above one can just leverage the public papers produced by bigger research labs.
I have the feeling that smaller players are about as likely to get past GPT-n family in the next 2-3 years as I am to turn a Farnsworth Fusor into a useful power source.
Major technical challenges that might be solvable by a lone wolf, in the former case to reduce the data/training requirements and in the latter to stop ions wastefully hitting a grid.
But in 10 years the costs should be down about 99%, which turns the AI training costs from "major investment by mega corp or super-rich" into "lottery winner might buy one".
Is it likely Google or others with large Research wings can compete with OpenAI? Very probably so, but Iām assigning a non trivial risk that the proverbial emperor has no clothes and incumbents like Google cannot effectively respond to OpenAI given the unique constraints of being a large conglomerate.
Regardless, time will provide the answer it seems in a couple of months.
