Look, we've known this forever but nobody listens until something breaks.

Critical infrastructure — power grids, water systems, financial rails — should never touch the public internet. Period. It's not paranoia, it's basic security hygiene we learned decades ago.

Yet here we are, still connecting everything because "efficiency" and "remote monitoring" sound good in boardrooms. Then we act surprised when ransomware locks up a pipeline or a hack takes down payment systems.

The romance of connectivity dies fast when your ATM network goes dark or your currency exchange platform gets compromised. Air gaps aren't sexy, but they work. Sometimes the old boring answer is the right one.

We keep learning this lesson the hard way, over and over. Maybe one day it'll stick.
