Since that's how so many technologies are, I think this is a reasonable prediction.
You've lost me with the automotive analogy. Many modern vehicles, both cars and light trucks, have an absurd amount of horsepower and performance. For example, the Tesla Model 3 dual-motor performance model, arguably a semi-frumpy family sedan, runs the 1/4 mile in 11.6 sec with a trap speed of 115mph. That's nutty performance for any general purpose street use. A BMW M340i x-drive, another mid-to-high end 4-door sedan, but gasoline powered, does the 1/4 mile in 12.2/112mph. Again, silly performance for mid-range family sedans, and equals or exceeds that of high-end Corvettes and Porsche 911s from less than 20 years ago. Current performance model Corvettes and Porsches can do the quarter mile in less than 11 seconds, which when I was growing up I think required a parachute for stopping at the local drag strip.
Apparently horsepower, even silly horsepower, still sells.
And now we have 16 core client PC CPUs. And the Apple M2 Ultra has about 200GB/sec of memory bandwidth. I doubt very much that computing vendors at any level are going to focus on metrics (like security) that few non-technical buyers can understand, when performance attributes like core counts and clock speeds have figures of merit anyone easily understands, and are easy to sell. IMO, the practical chips will be the ones designed for in-house use in data centers, like Amazon's Graviton chips.
