What guarantee do you have that any chip on any of your devices is not backdoored?

Conversely, what indication is there that Titan M is more likely than any other chip on any of your devices to be backdoored?

How do you suggest we prove this negative?

What indication? Basic common sense tells you it has to be backdoored. Look at what it is, what it does, who’s making it and who do they serve? It’s closed hardware for a reason. That chip is so backdoored I’ll wager the backdoors have backdoors. And that’s not even a joke.
