First, read my text fully before replying.
But additionally I have a brain and can use it to double check:
In example 1. I just build it blindly because it's a game and it doesn't matter if it's wrong. But it ended up being correct and I ended up having more fun instead of doing excel for an hour.
In 2. the math result was not far off from my guesstimate and I confirmed later, it was correct.
In 3. it gave me a source and I read the source. Google did not lead me to that source.
When I let LLM write code, I read the code, then I test the code. Here is where I get the most faults. Not in spreadsheets or math or research.
Whats so bad about Apache, MIT or Unlicense (which is essentially public domain) ?
If a company wants to monetize it, let them monetize it, if it fails, it still continues to be open source and can be used and developed by others. If they re-license it to something proprietary, fork it.
