I guess in the era of SSDs (vs. spinning disks) and multi-GHz cores, the startup really isn't a big issue anymore?

I wonder how long Teams or Slack would take to launch when it's on a 5400rpm disk on a 2000 era computer...

I remember my 2000 computer could play an mp3. But thats it. Your system is 100% utilized. No way it could even think about a modern gas guzzling app.
