Project Orion got me into programming at 13, no regrets since. I could create a premium plugin, get a job, or more with the knowledge I earned. I’d recommend the course to anyone who doesn’t want to wait to to create something. I see lots of criticism because Matej teaches using Foundation, if you don’t want to use Foundation, that’s fine. He teaches without Foundation too. But you shouldn’t harass him or do other bad things. It’s made to help you create really complex things without worrying too much about multi-version compatibility and other things so you can focus on actual development. You’ll eventually learn to make complex systems and other things without it. Like most people, they end making their own libraries.
