Are you sure that access will be democratized? What if you need $100k worth of equipment to run it, partially from a large number of weights, and partially because corporations drive spectacularly high demand on GPUs, driving the price higher? Just having the algorithm is not enough to guarantee it unfortunately.
At least some state actors will invest the very negligible money of getting to where gpt-4 is now. It does not need to be cost efficient to train or run.
It's total cost is not even near the scope of a space program or even a major military research project.
With 10-100 million dollars you can probably get most of the way there once it gets prioticed.
