Having people create new technology to avoid arbitrary legal hurdles instead of adopting existing and perfectly functional technology doesn't seem particularly efficient.
Why can't the market work it out on its own? People will buy superior products.
Governments mucking around with things like patents only distorts markets in ways that make them inefficient, and ultimately worse. Anyone who thinks the government's intervention improves things hasn't been at the business end of the government.
Trying to harp on anyone here about "efficiency" is going to fall on deaf ears.
Whether it's single passenger cars or AI, nobody really understands how inefficient they and their lives are.
The intent of the patent system is to encourage publishing innovation in exchange for rights to it for a period of time, and then everyone gets to use it. IMO the biggest problem has been granting patents for inventions that at least in retrospect seem non-novel or obvious. I get that there's a grey area there at some point, but "one click ordering" is one that comes to mind. Just because someone hasn't done it exactly like that before, should not make such a simple idea patentable. And I think patents should be on specific implementations, not general ideas. If I can implement the end-user experience of one-click ordering without substantially copying Amazon's underlying technology, that should be fair to do.
