I'm sure he's good at his job, but it does sound like a guy going "I've been a senior software architect for 40 years!" while spouting things so simple they border on platitudes. The way he just kind of dismissed Louis' point about Docker Compose bugged me greatly.
Even the dreaded AWS people keep invoking can be reasonably mimicked on a small scale, especially if you're an autist looking to resurrect your favorite childhood comfort game. The "there could be like 20 servers doing different things!" and "you expect people who won't even use linux to use
Docker!?" are absurd points; the future is now, old man, Linux VMs are easy to spin up and Docker has a fucking first-party Windows GUI these days. Just tell your fans how the game's API works
even if just at end-of-life and I promise with modern tech they can figure out the rest.
