With enshitification closing in on all aspects of the internet has the american tech industry ensured the internet will never evolve past where it is now?

I'm starting to feel like the Cyberpunk 2077 version of the internet is not too far-fetched. It's split into 2 parts:

1. The "old net" - This has been completely overrun by AI programs that are so fast and powerful they almost immediately compromise any non-AI powered system that connects to it.

2. The "net" - Blocked off from the old net by the "Blackwall" (a big firewall that keeps all AI out) is basically your standard internet that humans use via cybernetic implants.

I honestly could see AI basically filling the internet with so much garbage and malware that it becomes completely unusable. This is already starting to happen. However, if we create a new one with just human-controlled computers, I don't see how we could stop people from just connecting AI to that one.
