I work with 32MHz microcontrollers at work and you can do plenty with them. It’s a different world from say general CPUs where speed is king. You’re often more concerned about timing reproducibility than outright clock rates. There are also considerations about power consumption, electrical noise, functioning in extreme environments, etc. that may inform your decision to go with one controller over another.
I suppose Facebook, if only because it’s the hardest to avoid for me. Friends, family, local businesses, charities, bands I follow, bands I play in, friggin everything is on FB and the feed is such a cesspool at this point. And the only thing that might have a snowball’s chance in Hell of challenging its dominance is maybe Discord? Some of my friends seem to be spending more time there of late, and a few community groups I’m involved with have started their own too. But I dunno.
