Re: Great start, and then...
Note that software patents is mostly a US thing, so meh.
On duplication: AI is surprisingly competent at it. It still stumbles in the dark when writing code but the original software proves to be a good handrail.
In the last week I had Claude replicate pretty much all of the Erlang ecosystem including Elixir support for an experiment I want to run around variations on the core ideas in the ecosystem. The details aren't important, what is important is that my guidance has been very hands off and huge swaths got completed stand alone. Something I would not have dared to attempt in, say, January. All within my regular Claude Team seat.
My hypothesjs is that software licensing will be dead, commercial and open source. Not completely, but mostly. Just because the build-or-buy decision will be massively slanted towards build.
