It's well known in Corporate R&D that ever since UMB/LTE the modem performance is within a small factor (maybe 2x-3x) of the optimal shannon information-theoretic limit, so essentially, there are no tech innovations left to make. Qualcomm has pretended this isn't true by inventing buzzwords like 5G or 6G and producing standards with "fatter and fatter pipes" but bonding together 100 fiber optics cables is not innovation, and this is all that Qualcomm can hope to do, because the execs are too terrified to attempt to enter any other markets other than RF/Radio markets (of they tried with CPU's but chickened out with 64-bit ARM and I predict they will stumble again and fall flat on their face as soon as they have difficulty again)
For a short period of time (1993-2010), the wireless telecom industry had something akin to moore's law. Now, what they have is more akin to s'more's law (everyone sit around a campfire and eat marshmallows and complain about how great their job USED to be!)
