unless i can somehow set up a 5g local network, i don't see how this is true? there's got to be a million if not a billion wifi networks for various different applications (like gopros). i have nothing that speaks 5g yet, no use-case for it, and even if i did, no meaningful coverage. carriers might be hyping it, but it doesn't make it so. DSL is still a thing in some places. 1gig ethernet, 2.4 GHz wifi, and various other "old" protocols are still widely used. this will not change quickly, because they work. 5g currently doesn't. maybe this will improve in the next 5 years, but who knows if there isn't something better then? i don't even buy the premise that equipment with a current 5g modem is future-proof. this is what happens when technology becomes a marketing tool, and not something that solves a genuine problem (or the biggest problem i currently face). maybe it'd be different if i lived in a country with poor internet infrastructure, with 5g being my only hope for decent speeds? but even that is more of a prayer, because if decent wired internet doesn't exist, will decent 5g coverage exist? (by that i mean coverage with meaningfully faster speed and latency than LTE, with a choice of providers for competition?)
