Oh yes, the great old "works for me". On a yesterday's supercomputer, I presume? I live in a "developing" (have doubts it's really developing) country, most people are running laptops with no more than 8 GiB of RAM (sometimes it's 4 or less), and all this Electron nonsense is running like molasses, especially if you're trying to use a computer like a proper computer and do multitasking.
And most of the world is like that, very few of us (speaking globally) have $2k to drop on a new supercomputer every few years to run our chat applications.
