This is a major reason why consumer electronics and information technology have enabled so many more rapidly scalable businesses in recent decades than other industries (hence "We wanted flying cars, instead we got 140 characters").

The technology industry is uniquely founded on physical phenomena that are deterministic, even at high speed or recursive complexity (CPUs, storage, networking, displays, peripherals, etc). Therefore, if you can think of something in a mathematical fashion, you know that it can be built. This essentially eliminates technical feasibility risk - rather than worrying about whether a product can be built, you can focus on what should be built and why.
