For the development/application part? Let people race to figure out the best way to deploy things before someone else does, the way the swiss and Germans and Chinese did in the free for all time. I've heard competition be called something that incentivises people to find edges that aren't easily copied, and trade secrets can still exist
I think this is only true to a certain extent. We have reached a point where a lot of new innovation and invention is only possible with a truly tremendous amount of financial investment. No amount of tinkering in your garage is going to bring about the next advancement in EUV lithography. You need an entity with a lot of capital and a strong incentive to bring many of these things about. That can come from either the private sector or the government, but it cannot realistically be pulled out of thin air.
How can trade secrets exist if we are “just sharing ideas openly with each other”?
