This is one of the worst takes I've ever heard.
There's a reason industries have standards. If you replace established libraries with vibecoded alternatives you will have:
- less documentation
- less tested code
- no guarantees it's doing the right thing
- a dice roll for whether it works this time on this project
- a bad time in general
langchain is stuck in innovator dilemma - it was built for gpt 3.5, or 4, it needs a different design for todays models, but cant evolve because of existing users and backward compatibility
just like jQuery still exists and is being actively developed
