The thing I hate about Y2K is that it was taken care of so well beforehand that it is seen by many as having never been a threat – a punchline – with an effect of more people having less of mindset to prepare early to prevent other large scale catastrophes. Like, say, climate change or a pandemic.
"If I can't immediately touch the inferno raging three rooms away and burn my hand, then my home must be safe. Do I smell smoke? Someone must be smoking outside so I'll just yell out the window at a perceived inconvenience that is completely separate from reality."
