See, I look at it the opposite. Physics may limit any new tech, but really we havent seen any wireless advances, just wider bandwidth, higher modulation, more subcarriers. To me, a true advancement is an improvement without major cost. Everyone of those improvements tends to come at an SNR cost at minimum and SNR is something we are already losing. Sure theres improved SNR with moar power, but thats just diminishing the aggregate to improve the minute
