Electron apps are great themselves. It’s when you are in a 3rd world country where all computers are old or when you are working on an underpowered machine it becomes a problem. Spawning a new browser process consumes resources like there is no tomorrow or other programs running simultaneously. This is the problem Tauri addresses.
Developers can point at the issue. The less informed say "my computer is getting old" or "can you clean my laptop so it works faster". We're able to say "5 simple apps taking 24GB of ram is absurd".
Then that means we need to do a better job of informing the public about how wasteful our industry is being of their computers and, indirectly, their money. To do otherwise, to keep them in the dark, is disrespectful. My hypothesis is that once non-developers are informed, they'll care. They probably already feel that something is wrong but can't articulate it, and have perhaps resigned themselves to a crappy experience.
