It's quite rare for companies to fail because of one bad decision, but I believe that choosing python for large complex projects will have long term negative consequences, irrespective of whether it will on its own kill the company or not.

So do you think for example FAANG-like companies would have done pretty much as well if they wrote all their stuff in Scratch[0] instead, or do you think the choice of programming language matters?
