This misses the point completely. Regular security issues happen often, in 2023 alone we've already had 809 CVEs in Android [0]. Saying we should overlook addressing those because sometimes a CPU level security issue comes along is absurd. Spectre and other similar families of attacks are comparatively rare enough that they have names not numbers, that should say enough.
