idk if gaafet will come to consumers in the capacity finfet and mosfet have reached, gaa is a very supply limited substance in comparison!

What do mean substance? GAAFET(Gate All Around FET) is a design, not a material.

True that it's not a material, BUT there is a valid point that, such 3D ways of doing transistors are expensive to manufacture.
And we, consumers, don't like expensive things. We want performance/price most of the time.
Not a lot of us would be ready for a 4000$ CPU if it meant 30% better perfs over a 900$ CPU.

Different designs is how things have been moving forward and how they've been targeting the performance/price ratio. If the device does not require much processing power there are other processors still made on older nodes for a lower price point. The majority of pricing is in the machines, wafers and yields.

I think you might mean GaN which is a different semiconductor material they're using in some power supplies.
GAA stands for gate-all-around and describes the geometry of the transistors (the gate surrounds the channel on all sides, FinFET was just surrounding it on 3 side) not what they're made of
