I'd love to play with this but something freaks me out: we heard no later than yesterday hackers ruining tens of millions of food by heating connected fridges in supermarket in France.

What happens when people decide to hack the Unitree robots and have them pick up knives and stab their owner and then go on a spree in the street?

Before people say: "But that's never going to happen, nobody would ever do that!" I'd like to state again the fact that people did just remotely hack fridges to ruin food.

"But ruining food for everybody is nothing, it's just kids playing around, people would never hack robots to hurt other humans!".

Is that what people really think?

Or do they think that "this time programmers managed to create secure software that cannot be hacked into"?

Hacking into what exactly? It's entirely up to the user if they want to connect their robot to an insecure webserver control hub.

The difference between you and most professionals is that we don't play. Groceries weren't playing with their refrigerators, they were attacked, the government can find and punish or kill the criminals if they continue their pattern of failure to bring justice the world will move past them.
