Does anyone actually have faith in their hw+sw security these days? The speculative execution stuff on CPUs, system code full of buffer overflow / privilege escalation bugs, attacks that can work across airgaps using high frequency sounds, all the attacks on various hash functions, fake digital signatures, sandbox escapes, ... it goes on and on and each time you realise that it's been wide open for ages, and whichever security researcher found it could just as well have sold the exploit for lots of money instead.
Even as a fairly tech savvy guy I wouldn't actually know how to make a truly secure computing environment short of putting the whole thing in a silent Faraday cage and having metal detecting scans going in and out.
