I know chip and RAM fabs are incredibly difficult and expensive to build, but how is the several trillion $ out there just up for grabs for anyone that can undercut the like 4 companies that have one not enough for tons of huge companies to say “I don’t care what it costs, I don’t care what you have to do, because even if I pay 50x what it costs nvidia to make a fab, I will still be scrooging like a villain”?
So are we just kind of admitting that there exists no way to expose any networked device to the internet securely? Because if it’s not possible for PLCs I don’t see why it would be possible for any device. If water utilities have to take these offline, then how does that advice not apply for every internet-capable device in every commercial and industrial facility worldwide?
