Why Meterpreter isn't controlled by an AI or achieving some other autonomous state, I'll never know. Its like hackers forgot that viruses and worms were ever a thing, and yet therein lies the next big leap... lateral movement without c&c. Anyway, Metasploit has been with us a long time, and is a good example.
Other much earlier tools like nmap have lived through Y2K and are still in regular use to this day.
While the software itself has progressed a lot, their initial purposes have not left us. The same names always crop up when looking through decades-worth of hacker tools.
Everything about firewalls today, other than new lingo (like clouds) is pretty much the same. That is surely a stable technology that remains ubiquitous.
Look how old ISO2700x and 17799 standards are. They (one is really an "upgrade" of the other) are here to stay for a while.
