Elon Musk says that the speed of light in space is way faster than in terrestrial data cables

~100 lasers per satellite, each operating above 10 Tb/s, with over 100k satellites should be able to outcompete undersea cables.

Speed of light in space is ~40% faster than cable and the path is direct, instead of following the outline of land masses. https://t.co/l7aqDUoTAK
