Docker took off because Ubuntu can’t run current software. Now you need multiple copies of an up to date Linux visualized just to keep it interacting with old software on a base system we insist we need.

If all your docker images prove that an up to date Linux can run, then why not just make the main system up to date and you won’t need docker as much.

Ubuntu problems. Just use Arch. Then all of your software is from the same era… aka current.
