Yes, some people do novel problem solving with software. But it's super rare in the grand scheme of the millions of people in the world who program.
The devil is in the details - your mixture of features is different than mine. We have constant upgrade of video codecs that offer more capabilities. We have unavoidable security issues that need to be somehow addressed (by version upgrades or replacing some components). Etc, etc, etc...
IMO it is quite arrogant to claim "all problems are the same problem" - they are not even though they might look similar.
I don’t agree with this - the space of problems to solve is as big as that of solutions (both are programs in the end).
I don’t think suggestion about lack of experience deserves any response.
No, it means 95% of effort spent is spent towards already solved problems. This is, in part, why I hate capitalism. People are doing tons of work simply to compete with others instead of working together to solve meaningful problems.
BTW - lack of an authority deciding what problems are meaningful is the core idea of capitalism. And I'm telling you as a person that lived many years under communism: this is much better for everybody.
