Once, firewalls were useful for certain types of attacks. Now they're more trouble than they're worth -- and create a false sense of security into the bargain.
Firewalls need to go away. I'm just saying what we all already know. Firewalls have always been problematic, and today there is almost no reason to have one.
Computer firewalls have been with us since the 1980s. Even early on it was pretty clear that they didn't really work; if they did, we would have defeated malicious hackers and malware a long time ago. But at least back in the day there was a decent reason to need them.
