~ 1 GB/sec seems about right for a long time. I can't imagine the basic files I work with everyday getting much more storage-dense than they are in 2026.
I remember my friend Peter, in 1999, on campus networking with 100 Mbit internet saying: I think this will be enough for many years to come. And he was kinda right — 100 Mbit is still "almost good enough" 27 years later for internet access.
