My first PC ran at 16MHz on turbo.

PCs today are orders of magnitude faster. Way less fun, but faster.

What's even more orders of magnitude slower and infinitely more bloated is software. Which is the point of the post.

It's almost impossible to find any piece of actually optimised software these days (with some exceptions like sqlite) to the point that 99% percent of the software currently in use can be considered unintentional (or intentional) malware.

Particularly egregious are web browsers, which seem designed to waste the maximum possible amount of resources and run as inefficiently as possible.

And the fact that most supposedly desktop software these days runs on top of one of those pieces ofintentional (it's impossible to achieve such levels of inefficiency and bloat unintentionally, it requires active effort) malware obviously doesn't help.
