Exactly. While this speed vs space trade off makes less sense in mobiles, it might make perfect sense in industrial settings. Imagine 3D computers the size of a room (Craigh 2) but a 1000 times faster than any TPU only cluster.

If you can trade single-core speed for parallelism cluster of traditional electronics make more sense, but for some algorithms you can't.

Imagine a CPU with the complexity of Arduino but running at 100 GHz.
