Only ~14% of respondents had <=5 years of dev experience. And 55% were >10 years dev experience.
One thing I did find funny though was this survey found that devs overwhelmingly visit stackoverflow aka the site that puts the survey out found that so many people that use the site, use the site.
It does. Whatever they are, they aren't junior developers any more. As a hiring manager, I wouldn't hire a dev with >10 years experience into a junior role - if they're still at junior level, it's not that they're a junior, it's that they're unable to progress, which is a whole different issue.
I think the person you're responding to has likely read this quote or one like it, and perhaps you haven't? I assume that they're referencing it in an offhand way.
Since I started using ChatGPT, I rarely visit stack. If I need some code ChatGPT will tailor it to my example and I can get up and running quickly to figure out how it works.
