well, the same can be said of Swiss martial cutlery... To connect this a bit back to emacs, I think the big contribution VSC has made is to popularize the language-server concept, which decouples the UI from the automagical autocomplete and context-sensitive documentation we expect from IDEs. Emacs's lsp-mode and (I'm told, not yet tried) eglot make it possible to use emacs to productively write java, something I won't attempt without tooling support. The LSP interface, like slime, enables a whole class of interaction, rather than re-implementing the language support for each languge, like in days of yore. That truly is a modern coding practice, brought to emacs.
