Matthew Garrett examines
the factors that go into the decision about whether to install a
firmware update or not.

I trust my CPU vendor. I don't trust my CPU vendor because I want
	to, I trust my CPU vendor because I have no choice. I don't think
	it's likely that my CPU vendor has designed a CPU that identifies
	when I'm generating cryptographic keys and biases the RNG output so
	my keys are significantly weaker than they look, but it's not
	literally impossible. I generate keys on it anyway, because what
	choice do I have? At some point I will buy a new laptop because
	Electron will no longer fit in 32GB of RAM and I will have to make
	the same affirmation of trust, because the alternative is that I
	just don't have a computer.
