the most common complaint i see people have with Docker is the quip "it works on my machine => i'll ship my machine" but this is literally the _least_ of the issues with Docker
every new thing i learn about Docker and container infrastructure as a whole is somehow more upsetting than the previous one. the entire thing is bad. OCI is bad. none of it is well-designed, most of it makes barely any sense at all, hardly any can be reasonably run at scale
