Honestly all the "fancy new" stuff only gives you benefits at galactic scale compared to what most solo folks will build. You already start well behind the curve being a solo dev, so you lose out on a lot of benefits of orchestration, rapid microservice deployments, etc. That stuff is built for teams, not one person hacking away in their home office on nights and weekends. You get all the bad parts, because they can't be avoided, and none of the good, because you don't have the throughput to take advantage.
My current job has 80 or 90 devs and we have both on-prem k8s, on-prem monolith, and plenty of "cloud-native" AWS stuff. Everything TS, GraphQL, messaging queues, exactly what you'd expect from an organization that size.
My side projects are all .NET MVC apps. Full-page reloads, manual deployments out of Visual Studio, etc. The only excuse for me to go the TS etc. route would be if that was the only thing I knew how to do, and honestly with as much as I've heard from folks like Tony and Pieter, if I was green now and only knew TS, I'd probably be learning PHP and Laravel.
