CNBC
"Transcelestial is working on expanding in deep space and building the infrastructure that's needed for automation as well as maybe even human settlement in the next couple of decades."
Reuters
"The thesis back in the sixties and seventies was, eventually the size and the efficiency of the power of the lasers would reach a point where you could use lasers directly, wirelessly, to transmit data"
Rest of World
"99% of the world's data goes through a network of fiber-optic cables under the oceans and across continents. This is where the Internet Distribution Problem lies — in providing affordable, high-speed internet to everyone."
