Multi-sourced accumulated unmaintained amateur software without clear provenance or ownership is more like creating a feature I'll call "insta-legacy": now you're responsible for a bunch of code you didn't write that by definition nobody you have access to understands.
This is absurd.
It's not going to stop people from doing it. The industry is clinically insane.
It allows people who do bad work to do more of it quickly. Before they had to manually shovel garbage into projects but now they have a dumptruck.
You know what? It might be fine. Maybe we're going to have a world of fast food programming where minimum wage coders pump out trash and there's going to be Michelin star programmers where you go to for the real stuff.
If that's the case, we'll have to somehow educate the public on the difference so they don't think it's the same thing. McDonald's and The French Laundry are both successful restaurants. That world is possible in programming as well.
It might already be like that. The cheap rates for shady contracting firms that do trash work are probably already using these things
