Google: Software is never going to be able to fix Spectre-type bugs

Are Spectre-style bugs present on other processors like the ARM64 or POWER?

I have only skimmed these articles, but they address your question regarding POWER:

The _Talospace_ and _TenFourFox Development_ articles are by Cameron Kaiser, who is active on HN (and Blogger) as classichasclass.

*ARM processors with speculative / out of order execution are affected.

My understanding is that older A53 implementations of AArch64 / ARM64 are strictly in-order and thus not suceceptible to Spectre etc.

Any CPU with out of order speculative execution is probably vulnerable.
