In my experience more than 9/10 programmers I've worked with have never used Docker before and of those who have, the majority have never used Docker for anything personal.

If I hand them an image for a Dev Container, sure, they might use it, but it becomes "a thing we need to do, to compile our code in our IDE" not a tool they would use for isolation*.

*) OP seemed to imply that containerization would be nice for safety and security compared to bare metal, but containers were never built for isolation in the first place, mind you. They are namespaces and chicken-coop-like-jails at best.

I don't use them in the way the heavy docker users use them but I have been using docker and even earlier Linux on Linux container solutions for decades.

There was some user chroot thing early on that required me to make a library to intercept the setuid calls to pretend the garbage root-only build system was running as root on everyone else's lowly user account.

And that's not even including the myriad of distroboxes I need to do anything at all on my gaming pc.
