There's that, and then there's the other kind of negative work, whereby a rockstar engineer develops something that works but only he understands, completely failing to document it well.

I was thinking more of people burning stuff down.

There’s also people burning the furniture for immediate warmth.

And there’s people you mention who are doing things that look good but have time bombs inside them.
