And also an artifact of strategic choice of pursuit of these technologies. Due to the resource and scaling requirements (as well as inherent skill needed), replication of efforts for expansion purposes is difficult and that's one reason (not the only reason) these sort of modeling approaches are being pursued. A lot of technology choices are being chosen because of an inherent high barrier to entry, limiting competition risk.
