I haven't ever written professional software, but I just took a software engineering course and what I learned is that what technology stack to use is none of the clients business.
I just wanted to share this because I find it amusing til the moment that client went with another company that had "patent pending tech" and AI, it was sad because I knew the other company was just a couple of guys loading data.
I guess the lesson is that sometimes it's hard for people with a technical background to sell because we usually don't "hype" our tech.
