No, the poster is saying that latencies are about 100x the theretical minimum latency due to speed of light, and thinks that will reduce to 10x.

I don’t know if these numbers are true, but poster was not claiming faster than light.

There are several reasons why Internet latency is inflated over direct-route speed-of-light latency. Some reasons may change others may not.

1) speed of light in fibre is 2/3c - unlikely to change soon 2) fibre is laid in the ground on a circuitous route - rarely changes but does happen 3) queueing delay - that's often the main culprit, changeable, but hard (see the buffer bloat debate)
