Exactly. This is far outside my professional field, but lately I've found that one of the better ways to read the tea leaves of the next decade is to look at the boring 3GPP/ETSI material rather than the consumer-facing "6G/7G" discussion.
The interesting part of 6G doesn't seem to be faster downloads so much as sensing. ISAC is basically about making the network capable of sensing the physical environment as well as communicating.
Some of the current work is already discussing the "six sensing modes", involving different combinations of the network and UEs transmitting and receiving signals reflected from objects, and even how users might be incentivized to let their devices participate
That feels potentially much more consequential than another speed bump. 3G/4G didn't just make phones faster; they enabled an entire ecosystem that was hard to predict beforehand. My guess is that sensing could be a similar pivot for 6G.
Also if I had a dollar for every end user residential consumer (as a person who runs ISPs) that confuses "5G" with "5 GHz wifi". Like, when your install techs have to explain to a customer why they're getting shit performance in the default 20MHz wide 2.4 GHz channel, and to reconfigure all their devices in a house to talk to a 802.11ax/802.11be 3x3 or 4x4 80 MHz channel AP in the 5.x GHz band.
Consumers literally don't know the difference between cellular/LTE carrier "5G" marketing and the "5 GHz" band on their home router now.

Why would they know the difference? They don't have any technical appreciation of what either term means or its implication for what the hardware actually does; the terms sound similar; and they've been trained by decades of marketing to choose bigger numbers[1].
