Today. Today has never been a good target when planning builds that
need to last the next decade. Fibre affords us the luxury of sufficient
capacity to reduce the infrastructure churn where we choose to.

That's a separate matter and needs addressing whatever the delivery
technology and speed.

I got "how can we monetise latency", says it all, nothing gets fixed
without a premium and the way they were talking that means most do
not get the fix as it becomes an incentive to increase latency to force
more payment. The speed is immaterial in that.

So? Some companies will find ways to do things badly regardless, others
make best of what they have. Nothing to get annoyed at nor an argument
to not build faster networks.

I think I may mave missed your point. What are you suggesting, we don't
build faster networks? A new (faster) network build is a great opportunity
to fix bufferbloat.
