The web hand may change quite a bit, webpages would load faster, it would be safer (malware would lose an entry vector), many shady practices would cease to exist (Linkfarms, DNS parking, DNS redirect, dark patterns, browser start page and search engine hijacking, click bait, ...), tracking and user profiling would lose justification, centralizing everything in the hands of a few would become expensive, and a few other things.

But the internet? I guess it would be unchanged and unfazed.
