More of a personal/situates POV, my previous comment was a bit rashly worded.

From where I stand, it's yet again another useless trend generating e-waste.

Like "oh look with 5g you'll be able to load netflix and pornhub in 10k very ultra mega high hd on your tiny phone screens, you really need it and you need to ditch uour old phone before its end of life and to buy a 5g one".

They even tried to sell it as philantropic " thanks to 5g, poor people in poor countries [insert picture with black people here] will have access to good doctors from good places for surgeries [insert white old dude in a white coat picture here]".

And it opens a whole new field of connected items which sounds really nice in terms of corporate/state spying.
