It will be shoved into your life anyway. You might like it or not, but the only safe choice is to learn and understand it IMHO.

About usage: it looks like web development gets benefits here, but other areas are not that successful somehow. While I use it successfully for Neovim Lua plugins development, CLI apps (in JS) and shell development (WezTerm Lua + fish shell). So I don't know if:

a) it simply has clicked for me and it will click for everyone who invests into it;

b) it is not for everybody because of tech;

c) is it not for everybody because of mindset;
