Basically if someone has physical access to device, its game over.
You can do things like efuses that basically brick devices if something gets accessed, but that becomes a matter of whether the attacker falls for the trap.

It took more than a decade to exploit this vulnerability and even then there are fairly trivial countermeasures that could have been used to prevent it (and that are implemented in other platforms.)
Nothing is unhackable, but it requires a very peculiar definition of "game over".
(And as others have pointed out: only early versions of this Xbos One where vulnerable to this attack.)
When it comes to SOC security, the past is not a good predictor of the present. The previous Nintendo SOC was designed 15 years ago. A lot has been learned since. It's become increasingly harder to bypass these mechanisms.
The fact that it took 13 years to hack the Xbox One is not because it's not an attractive platform: because of its high profile, it has been a popular subject for security research grad students from the moment it was released. And if anything, the complexity of the current hack shows how much SOC security has progressed over the years.
If your argument is that you can't hope to close every door, then AI will make it easier to close all the doors in the future.
AI could also make it easier to open the doors too.
