Only upgraded from Wi-Fi 4 (which I had since 2015) to Wi-Fi 6 recently. Most routers that support 160 MHz are twice the price of 80 MHz counterparts. 6E with its 6 GHz is another third of the price.
Wi-Fi adoption is usually extremely slow. Wi-Fi 4 was already 6 years old, but my router was the first in the apartment building to use 5 GHz.
To this day 2.4 GHz has wider adoption in my apartment building than 5 GHz. And my Wi-Fi is the only one with WPA3, which is already 6.5 years old standard.
I wonder when will we see wide adoption of Wi-Fi 8 - 15 years from now?
