All over a connection that isn’t shared with your neighbors.
Every home gets a dedicated 4-strand fiber line. Point-to-Point. Not shared.
"dedicated" to where? Because you sure don't get a "dedicated" line to every server on the Internet! That's just not how computer networks work. It's obvious that if you have 1000 homes with 25G links you'll need 25T of bandwidth to be able to handle them all at full speed with no oversubscription, but no router or switch currently in existence can do 25T on a single link.
Edit: Do people here seriously not know how the Internet actually works!?!?
