> And in 45 years of using computers this has always been the case Yes, because you presumably do your computing mostly behind some kind of NAT most of the time, and without any un-patched devices hanging out on the same LAN segment, and so there's no path for worms to have ever reached you by. That's not necessary true for the average computer user, though, who connects to shared wired or wireless networks at an office/coworking space/internet cafe/university campus/etc. Those that do this may end up with either/both of 1. a public-routable (usually IPv6) address for bots and worms to talk to, and 2. a link on a multicast-routable subnet with other already-infected devices. Also, a few years after you stopped using Windows, cryptocurrency was invented, which "changed the game" for cybercriminals in a lot of ways. Fun, meaningless, low-penetration cyberthreats don't exist any more; as "hacking groups" are now motivated by "real money" to get root on every PC they can so they can deploy crypto-miner background services, encrypt files and hold them for (cryptocurrency) ransom, exfiltrate the user's own crypto-wallet private keys, etc.
