Define “Internet” to answer your question more meaningfully.

Are you counting cached copies of data (Cloudflare etc), or only the original copy? Only the source data or the data copied on the receiving end (webbrowser etc) too? Data at rest on a computer hard drive or data being transmitted or both? Are you only including world wide web (websites) or any data (gaming, streaming, fileshare). Humans or bots or both? Public web or dark web? Any computer physically connected to a network or only those data accessible publicly?

Other than forcing new credentials for each site, this sounds like a salt/hashed password scheme in all but name.

The typing is the means of communicating the thinking. If you are “doing the thinking” and the AI is doing the “typing” then either you are instructing the AI to generate additional content without original thought (which is a waste of your time, the AI’s time, and the reader’s time), or the AI is actually doing some of the thinking (in which case your job can be automated).

The programers use AI to make art. The artists use AI to write. The writers use AI to program. I think we’re all in denial by both just how much our own value is at risk, and also the real value of AI (less than advertised). A bit paradoxical.
