When I need Gigabit between computers, I buy my own Gigabit

no need to have that as standard on the router.

it is when you have internet speeds of 100mbit or faster,

Except these routers are given to people with speeds under 100.

gigabit is cheap and people eventually will upgrade, especially when
all it takes is a phone call or clicking a button online.

And waiting for newer technology and probably new cables or fibre to be
laid for hundreds of miles under the roads.

The fiber itself is reusable through multiple
generations of terminal equipment. Once the single mode
fiber is in the ground, it can be reused again and
again as the terminal equipment gets better.

You can run the same fiber at 1Gbit/sec, 10Gbit/sec,
40Gbit/sec, or 100Gbit/sec. You can multiplex 40 "colors"
of light in the infrared, all on the same
single-mode fiber. (The equipment on your pedestal
right now, is likely using two colors.)

Useful technologies are available now, today, to
do this stuff.

Doing so, makes the terminal equipment, more and
more expensive. In the past, only undersea cables
did some of the above.
