While the broader cybersecurity field has seen rapid advancements, such as AI-driven endpoint security
Ya, about that "AI-driven endpoint security", it does a fantastic job of generating false positives and low value alerts. I swear, I'm to the point where vendors start talking about the "AI driven security" in their products and I mentally check out. It's almost universally crap. I'm sure it will be useful someday, but goddamn I'm tired of running down alerts which come with almost zero supporting evidence, pointing to "something happened, maybe." AI for helping write queries in security tools? Ya, good stuff. But, until models do a better job explaining themselves and not going off on flights of fancy, they'll do more to increase alert fatigue than security.
Widespread IPv6 adoption is right there with the year of the Linux desktop. It's a good idea, it's always Coming Soon™ and it's probably never going to actually happen. People are stubborn and thanks to things like NAT and CGNAT, the main reason to switch is gone. Sure, address exhaustion may still happen. And not having to fiddle with things like NAT (and fuck CGNAT) would be nice. But, until the cost of keeping IPv4 far outweighs the cost of everything running IPv6 (despite nearly everything doing it now), IPv4 will just keep shambling on, like a zombie in a bad horror flick.
