1. vi is everywhere, and...
2. vi with no plugins is still super powerful, which is helpful on random hosts / coworker's machines / basically anywhere, and...
3. since vi is still so powerful out of the box, i only need a few lightweight plugins to close the loop and make the most powerful editor i can imagine needing. 99% of my plugin usage is fzf and ale w/lsp, which are arguably two very powerful plugins, but the cognitive overhead is very low, and at least among peers my editor doesn't seem to be slowing me down at all
i would also pose the controversial opinion/hot take that using a less "powerful" (non-IDE) editor helps you write better code. humans can only fit so much into their working memory at a time. vim doesn't really let me do crazy refactors or jump through endless chains of class hierarchies (well, with lsp it can, but...). compared to my eclipse/intellij days (and codebases worked on by other people using those tools) i am forced to tame complexity by defining good module boundaries and abstraction barriers.
