> Yes, I might have phrased it better, but the intention was that at a younger age, you perhaps didn't yet have to upgrade a legacy projects with semi-obscure tooling where the original developers have long left; or have had to hack your code in a dirty way because the team leader might have read about e.g. an experimental frontend framework and a DB system that is in alpha status, but still orders the team to use it (to show the company that he/she is using cutting edge tech), so 80% of the time you're just figuring out how to get the system running instead of actually creating value for the project. You're conflating age with experience. Yes, somebody that's younger is likely to have less experience, but the two words are not interchangeable. Their link is definitely not strong enough to begin guessing peoples' ages based on their level of expertise.
