Probably will not. It’s a sign of the times, more memory used. Before Emacs was blamed as resource hungry, for similar reasons:
Chrome (or some other slightly better web browser, like Firefox), is not fully to blame Websites are now more resource-hungry, as JavaScript is used and it’s a Turing complete language (ok, Google’s V8 JS engine made it really practical to use JS to a large extent), so you CAN’T limit memory without killing tabs, or, in case of IDEs, extensions. Windows 98 had “16 MB of system RAM” requirement and famously came with Internet Explorer 4, so web browsers necessarily do not need much memory… (w/o JS). Older Windows was limited to 2 MB and had IE available.
We’re never going back to small, e.g. as modern browsers with fast JavaScript need MORE memory to be faster as they compile (just like Julia, we shouldn’t be throwing stones in a glass house).
Since the IDEs are really web browsers, with all those capabilities, I foresee videos in some ads for extensions (or built in tutorials)…
I see Theia works, but some issues, and link from there to an issue:
