The graphic at 13:25 re current (2019) PC hardware is interesting: * Bus between CPU and South Bridge not protected. * Most of Intel's "secure boot" functionally implemented in South Bridge. * At boot time, CPU asks South Bridge ... whether it needs to secure boot. * TPM chip connected to CPU through insecure LPC bus. Any TPM measurement can be forged. Maybe they meant 'current' when the Xbox One was being designed? Edit: at about 40:30 they say, 'a lot of this is still true'.
