Software is different. It's an implementation not an idea. You can't compare it to math, computer science, and physics, because irrelevant details matters.

Software is build relative to other software and used relative to other software. If you reinvent something already in use that is slightly incompatible with what already exists, you must also recreate all the other stuff from scratch.

Constant reinventing in software that starts from scratch with simple and clean software, then decade later it's finally useful but full of cruft just like the previous innovation with little or no benefit over it.

Another problem with software is the amount of uneducated innovators. Starting from 'scratch the itch' and not doing research is not a good idea.
