“I'm focused on restocking the shelves, hiring employees and selling lottery tickets. And asking them to defend against a potential nation-state adversary is a huge ask. It's like asking your neighborhood police force to defend against an army from another country.”

It's like asking your neighborhood police force to defend against an army from another country.

Dave Bittner

So how do you suppose the industry is going to respond to this? You know, both the cyber industry and the folks responsible for the refrigeration units themselves.

Chris Grove
