I’ve been in IT for 20 years myself, and I agree with your assessment. I remember wiring my first fiber bundle between two office buildings and thinking, “My God, it’ll never get faster than this.” And then it did.
The speed things are going, I wouldn’t be surprised if every human being is granted an IPv6 address and a NAT device when their born for all of their electronic needs. Hell, in 25 years, they’ll be talking about how IPv6 is almost exhausted and we need to go to IPvX with a 512-bit addressing scheme (shudders).
And Cisco will be offering a 35% discount on their new, "wirespeed" "Ultrarouter"....500TBS, per port, simultaneously. It will sympathize with you and automatically conjure up holographs of your favorite Victoria's Secret model when you enter the datacenter. CLI will be a distant memory as this router will be programed via interaction with said holograph.
