I don't think it necessarily scales that way. Larger organizations need more communication channels and coordination. If anything, assuming AI does give you 10x ability, there's probably a sweet spot where you have just enough developers that churn out code at a good pace but not too many that it gets too chaotic.
If you compare one developer to 10, for instance, one developer doesn't have to deal with communicating with 9 other people to make sure they're working on things that align with the work everyone else is doing. There is no consensus that has to be reached. No meetings, no messages that have to be relayed, no delays because someone wasn't around to get approval. That one developer just makes a decision and does it.
There are lots of big companies out there and in the past, small startups have been able to create successful products that never would have been created at the big company even though the big company hired way more developers.
