Silly post. Visual Studio Code also uses Electron, and has yet to spin up fans on my machine. I use it every day, all day, on a variety of platforms. There seems to always be someone who thinks there clever complaining about bloat and then pointing to C or now trendy Go and/or Rust. It rarely is. Perhaps Slack was doing some sort of internal auto-update when the CPU started thrashing. Of course figuring that would kill a good blog rant about bloat. I sure hope the author doesn't run Windows.
