The 'practical' way to beat fiber optics is to use either
(i) a series of overground direct microwave connections (often used by trading firms)
(ii) a series of laser links between low altitude satellites. This would be faster in principle for long distances, and presumably Starlink will eventually offer this service to people that are very latency sensitive
