Why Cyber Security for Operational Technology? Why now?

We know that cyber security has been a trending topic as per our previous post, and yet its as if there's no single time or event you can point to that says "okay, we really, really need it now".

Even after major hacks like Stuxnet, Saudi Aramco hack and the more recent Triton despite creating physical threats to human life it just hasn't been enough to push it alone.

We do know it is trending so what gives?
