I agree, along with a huge range of parallel machines. Parallel machines weren't a great idea in the early 90s, because you could barely get one decent CPU on a chip and adding memory turned it into a large board per core. Now you can have satisfying numbers of CPUs plus memory on a single chip, and even a useful prototype on an FPGA.
