I find it really fascinating how a completely different subset of Hackernews users answers to you than are present on other threads. As literary no sibling is voicing a dissenting opinion I feel compelled to present it:
Purely from the user perspective I hate electron, because of its RAM usage. The speed argument is a straw man: Of course V8 is fast. And yes, VSCode is a very good IDE. But the problem is real world electron application don't scale down. In my (of course biased) experience even simple electron applications use at least half a gigabyte of RAM, often a whole gigabyte. If you're on a beefy 32gb machine you'll never noticed the difference. But on the 8gb machines most people around me use, these electron apps really take up a huge fraction of RAM. And swapping is definitely noticeable slow, even on SSDs. The "think about the planet" argument comes to play, when I need to upgrade my PC because RAM is the bottleneck. And seriously what fraction of the population even has the knowledge to only upgrade the RAM and not buy a whole new PC.
If I had to advise you personally, I might even tell you to choose electron. But be aware that you are using the "defect" option in the prisoner's dilemma: as everybody around you is choosing the societally harmful option of wasting resources you are at a competitive disadvantage to do the right thing. And also: electron has stolen mind share off of better solutions, so the documentation there is also not in the best place.
And even worse, those people I reach with my argument, and thus put at a competitive disadvantage because they are going the extra mile to do the rights thing, might be those that I want to support the most, because they might be willing to the right (IMO) things at other topics I value as well, like the importance of privacy.
So what is the conclusion? I have no idea how to fix our collective resource waste and it is hard to assign individual responsibility and I'm deeply dissatisfied by the whole situation.
