At some point you have to learn to take critical feedback about yourself and not shut yourself down or vehemently keep repeating the same thing using different words. You are making immature statements like - Time to learn a technology and familiarity with a stack are not technical considerations. I expect a junior engineer to make such statements but not a senior engineer or a hiring manager. These are critical technical considerations when choosing a technology. Your statements show immaturity - period. If a director of engineering asks an engineering manager if he will consider the tech stack familiarity and learning curve for the team when choosing a tech stack and the manager responds in the negative, trust me - he will start looking for a new engineering manager. You are fixated on picking the "right technology" while your team loses momentum and attrition sets in. You sound like you think your technical decisions are unbiased, but Zuckerbergs decision to use PHP was biased. It is obvious why Zuckerberg used php. He was familiar with php and that was the fastest way for him to build a website. But according to you he made a terrible technical decision and he should have used something else. This is an immature statement. BTW, Facebook still runs on php. A piece of advice, do not try to impose your biases - technical or otherwise on other engineers. They will do what they want to do. If you join a team and they do not share your technical biases - you have 2 options 1. Show them why the technical choices you propose will help those developers in the long run. 2. Join a different team which shares your bias Badgering them with your opinions is not an option. Your options are - Show the developer why building Arduino copilot is not in his long term interests. The other option is - Galois is making tons of money by building copilot for safety critical embedded projects for NASA. May be you can also talk to NASA and get them to shut down the project. Otherwise you are just wasting your time and everyone else's time.
