The problem is that they become a buzz word for at scale companies that need them because they have huge complex architects, but then non at scale companies blindly follow the hype when they were created out of necessity for giant tech stacks that are a totally different use case.
They add a lot of overhead and require extra tooling to stay up to date in a maintainable way. At a certain scale that overhead becomes worth it, but it takes a long time to reach that scale. Lots of new companies will debate which architecture to adopt to start a project, but if you're starting a brand new project it's probably too early to benefit from the extra overhead of micro architectures.
Of course there are pros and cons to everything, don't rely on memes for making architecture decisions.
I guess I'm not sure how others build with micro services, but using AWS SAM is stupid simple, and the only maintenance we've ever had to do is update a Node version. 🤷
