Evolvable hardware has the same limitations. Good FPGAs aren't free or even
cheap. The limitation is transistor count and transistor technology, not
how the transistors are arranged.

First, that doesn't really answer the question, and second, I would have to
ask "fast at what?". Are you really going to claim that dollar for dollar
an FPGA can do everything a CPU/DSP can and faster? The current state of
the computing market isn't completely arbitrary. Transistor for transistor,
FPGAs offer few advantages (speed or otherwise) outside of specific niche
markets.
