Yes all modern console RA systems have a verified boot rooted in hardware that chains to a hypervisor. They also encrypt all code and network traffic, use revokable per-CPU hardware keys, and can tie game releases or updates to revokable firmware versions.
The underlying architectures are quite complex but there are some good tech talks about them online. One of the best is by Tony Chen, which covers Xbox One security. It's many years obsolete now, but even that security system wasn't cracked until long after obsolescence. Microsoft have proven you can build an effectively unbeatable security system for general computing devices even though they only use it for games and multiplayer anti-cheat. It seems Sony might have not reached Microsoft's level.
Maybe AI will speed things up by making it easier to find obscure bugs, but design wise the architectures are sound and can work well.
