It's going to be a lot less than 24ms though because that's the antipode which is worst case for a around-the-globe signal. However, the antipode for probably every single stock market is likely somewhere uninhabited. It's still going to be a huge improvement of course but I'm sure there's encode/decode times to convert to/from an electrical signal. And presumably the 0.1 bps probably means it also takes a long time to receive a single packet (error correction & collecting enough signal in the first place). So we're probably a long ways away from it making sense for that use case.

Also, the latency difference is a lot higher than 24ms because the current best route is via a circuitous fibre link. Light is slowed down in the glass of the fibre significantly (about 30 to 40%).
