I'd like to think these ideas have been around and well-known for decades, and we're starting to see the hardware rise up to support them. If you told someone in 2001 that Linux would be rewritten in say, Java, with a garbage collector it would have been dismissed as starkly inefficient. Nowadays we have hardware that makes certain safeties negligible on performance (memory tagging, bounds checking, etc). Nowadays we can make an OS out of Java and it will stand just fine. Or Rust. Faster hardware means we run slower (and safer) software. Not everything gets isolated into an ASIC, of course.
