> or keep your software fully proprietary and closed.

I guess it depends on your intention, but eventually I'm not sure it'll even be possible to keep it "fully proprietary and closed" in the hopes of no one being able to replicate it, which seems to be the main motivation for many to go that road.

If you're shipping something, making something available, others will be able to use it (duh) and therefore replicate it. The barrier for being able to replicate things like this either together with LLMs or letting the LLM straight it up do it themselves with the right harness, seems to get lowered real quick, massive difference in just a few years already.
