>This isn’t true - note how similar vulnerabilities have occurred on ARM, POWER, etc.

I understand you're trying to argue against my main point, which is:

>ISA complexity breeds microarchitecture bugs.

And definitely stands.

From there I have no idea how you derived that bugs are impossible under a simple ISA, which is implied in your statement.

As an added note: ARM in particular isn't simple. It's simpler than x86, but that's a low bar to meet.

>even if you weren’t wrong, it would be off-topic

We will have to agree to disagree on this.
