You are making it sound like it’s a fault of managers and coworkers that they don’t want some cowboy coder to replace everything that’s not on a stack they consider cool anymore with their version of “better”, which is probably some half baked idea that takes 4x longer than estimated to finish, missing 75% of the business cases, has a bunch of bugs and UX problems, has had little thought to testing, deployment, rollout or user training, and will have a huge opportunity cost on actual customer demands, but hey… “it works on my machine”. Cause all that is what I think of every time some junior dev starts complaining that everything sucks.
