Yes completely impossible to fake by design. Otherwise whats the point? But I think the root of trust is whatever signs the hardware TPM module. So, Intel, AMD and Apple.
If I understand it correctly, the secure chain of trust will be something like, hardware TPM module -> secure boot -> windows signed kernel -> Chrome (signed binary). Its not clear to me if desktop linux will be able to participate in this ecosystem at all - which is ironic given how much google uses linux. Maybe a couple of the big distributions like Canonical will be able to sign their linux kernel builds.

Its opt-in by website operators at least. Assuming this happens, there are two big questions in my mind:
1. How much of the web will go dark to anyone not using a corpo software stack? I imagine bank websites will adopt this technology immediately, while sites like HN, personal blogs and wikipedia won't touch this stuff. How much of the web will stop working on my terrible "hacker" computer where I use firefox on linux?
2. How will this interact with browser extensions and dev tools? If websites won't function outside of chrome, will we be able to continue to drive chrome programmatically? Will chrome's dev tools still work? Will websites be told about my ad blocker extensions? Will webdriver (and similar tools) be blocked?
