It doesn’t bode well. Honestly I fear at some point in the future, if these countermeasures can’t keep up, small sites may need to close themselves off with invite-only access. Hopefully that’s quite a distant future.

That’s actually a major plot point in Cyberpunk 2077. There’s thousands of rogue AI’s on the net that are constantly bombarding a giant firewall protecting the main net and everything connected to it from being taken over by the AI.
