Nah wifi was actually originally on 5GHz spectrum, with 802.11a. It came out shortly before 802.11b, which used 2.4GHz, and was objectively better…but component shortages for 802.11a devices made the inferior 802.11b more successful on the market.
Then in 2009, after 802.11b and 802.11g came 802.11n, which used the 5GHz spectrum, and introduced dual-band routers to consumers.
Most recently, 6GHz got allocated with the advent of Wifi 6E and Wifi 7.

Current generation wifi 6E and 7 add 6Ghz which offers substantially more bandwidth / speed.
Wifi 7 also allows devices to use 2.4/5/6Ghz at the same time instead of just hard switching between them.
Would be a major setback since 6Ghz allows devices to easily hit Gigabit speeds wirelessly.

Yeah, I’ve got Wifi 7 set up an it’s awesome. I’ve got a single access point, and I get full gigabit in my office with line of sight, and it auto switches to 5GHz or 2.4GHz when I move too far away. It’s also great for apartments since it’s more easily blocked by walls, there’s way less interference from neighbors.
