I really appreciate tooling that is written in Rust or Go that produce single binaries with minimal runtime dependencies.
Getting tooling written in for example Python to run reliably can be an exercise in frustration due to runtime environmental dependencies.
Why have an OS at all if every program is just going to package everything it needs?
It feels like we cheapened out. Rather than get good & figure out how to manage things well, rather than driver harder, we're bunting the problem. It sucks & it's lo-fi & a huge waste of resources.
The impetus for dynamic linking on Multics and MTS was the ability to upgrade libraries without having to recompile software, and to reuse code not originally designed or intended for (e.g. different compilers or languages), let alone compiled with, the primary program. Both of these reasons still pertain, notwithstanding that some alternatives are more viable (e.g. open source code means less reliance on binary distribution).
"the primary program" is the atomic unit of change, it is expected that each program behaves in a way that is independent of whatever other files may exist on a host system
