One unpopular opinion I hold is that in recent times programming became a lot more about integrating libraries and frameworks vs writing your own thing. This was fine because if someone open sourced it, why repeat the same work. That ended up in cases where a lot of work was modifying the libraries to your use case.

With vibe coding, I suspect this is a group that has adapted to it really well (alongside hobby coders and non coders). The thrill comes from problem solving, and when you can try out the solution quickly and validate, it is just addictive. The other side is how open source frameworks have increased, and there are a lot of oss libraries for just about everything. (A personal experience is implementing Cmd bar (like linear) in react when i was just learning. It took me a week or so, and then i just inserted an oss thing for comparison. It was super smooth, but i did not know the assumptions. In production, i will prefer that, and dont always have time to learn and implement from scratch). We see this with langchain etc in LLMs too, and other agentic frameworks as well. The shift is not towards less code but getting the thing to work faster. Claude code accelerates that exponentially as well.

Unpopular opinion would be that if the project is not much more than a bunch of libraries/tools/techs integrated together than the need for its existence is questionable. Diversity there breaks "one way of doing things" and makes it harder to learn actual tech that makes it work.
