Ask HN: Are we overcomplicating software development?

I have recently been involved in the overhaul of an established business with poor output into a functioning early/mid stage startup (long story). We are back on track but, honestly, my lessons learned fly in the face of a lot of currently accepted wisdom: 1) Choose languages that developers are familiar with, not the best tool for the job 2) Avoid microservices where possible, the operational cost considering devops is just immense 3) Advanced reliability / redundancy even in critical systems ironically seems to causes more downtime than it prevents due to the introduction of complexity to dev & devops. 4) Continuous integration seems to be a plaster on the problem of complex devops introduced by microservices. 5) Agile "methodology" when used as anything but a tool to solve specific, discrete, communications issues is really problematic I think overall we seem to be over-complicating software development. We look to architecture and process for flexibility whe
