100Gb exists, I presume it's trunk lines between major providers like Telcos...
We support 40Gb/s clients at work. That's 4000MB/s to the client. To support
that data rate the storage STARTS at $80,000. For $2.5 million we have a system
that will do 192,000MB/s. You get 2.5PB of storage at that price point.
If you don't mind the system being a little slower (25,600MB/s) you can get a
lot more storage, 10.6PB.
That's raw storage of course, data protection eats up some of the usable space.

Ciena sells a lot of spendy 40Gb optical link gear, it's particularly in demand

NOT an option. I'm sure 100Gb is under active development. Terrestrially,
you just run more 10Gb lines in parallel and use link aggregation.

To whom are 'you' talking that fast? The ISP is just the man in the middle,
they count on the net aggregate being something they can handle, that the
two endpoints, collectively, don't/can't saturate the fabric too much of the
time.
Of course, staying ahead of that curve IS their business.
