Look, your PC and BYODs are still prone to attacks, they're much much more powerful than those networked IoT devices, and they still need firewall to protect.

Look, your PC and BYODs are still prone to attacks, they're much much more powerful than those networked IoT devices, and they still need firewall to protect. I of course hope all firmware will be safe, and they should be safe as much as possible, still, you need a more powerful device to safeguard them. Put another way, no matter how secure my wifi-bulb is designed, I'm not going to expose it to the internet, and I will put it behind my firewall/NAT-router.
