This would be disastrous for actual manufacturing because a patent is the only thing that makes it worthwhile to spend a bunch of money upfront to develop a new technology. Unlike with software where you don’t have nearly as much up front capital investment to develop something, it costs millions of dollars to get a manufacturing process up and running and in a good enough state to where it can actually work out financially. Without patents, your competitor can just take all of that work and investment and just copy it with the benefit of doing it right the first time, so they’re able to undercut you on cost. The alternative is that everyone is super secretive about what they’re doing and no knowledge is shared, which is even worse. Patents are an awesome solution to this problem because they are public documents that explain how technologies work, but the law allows a monopoly on that technology for a limited amount of time. I also feel that in the current landscape, copyright is probably also good (although I would prefer it to be more limited) because I don’t want people who are actually coming up with new ideas having to compete with thousands of AI slop copycats ruining the market.
TL;DR- patents are good if you’re actually building things, tech bros are morons who think everything is software.
Okay so at what point does it get handed off to private industry unless the government is just in business with manufacturers in a much more direct way than it is now? We’d need a completely different economic system for all research to be publicly funded. Consider this- often the way it works now is that a government funded researcher discovers a new molecule that could be useful. Then, private companies figure out how to make it industrially and run trials in pilot plants and design the plant to make it at scale. Should the government be doing all of that? This is extremely expensive, and I don’t know how you’d try to prioritize resources in the current economic system.
