> but they could have been just as successful using another language. I don't claim to be a rockstar developer or anything close. But my capabilities and efficiency as a developer are tightly coupled to the tech stack I use (not just language). I moved from a job where I chose my own tech stack that I iterated over several years to one where I'm forced to use (IMHO) tools that are poorly suited to my work, and I'd say the quality and volume of my work has dropped by at least 10x. So I think it's both. You need smart people, but they also need to be using the right tools for the job.
