From McLaren Stanley's epic Twitter thread about an engineering near-disaster at Uber:
So my advice. Everything in Computer Science is a trade off. There is no universally superior language. Whatever you do, understand what the tradeoff[s] are [and] why you are making them. Don’t let it descend into a political war between opinionated factions.
Build in failure points. Figure out how to identify the tradeoffs and give yourself a way out if you get to a certain point a realize that you made a mistake. Big efforts are hard, but the cost grows the longer you make the wrong trade off.
Don’t be a Curmudgeon who doesn't contribute to the solution. Don't be a Zealot who creates bigger problems for everyone else. The best engineers I’ve ever worked with are really good at not falling into either of these traps.
