Or we need eyes that can drive a physical response faster & more accurately than a human can react. This is the whole robotics/drone/hardware market.
Right now, most of these efforts work at the same speed humans work (probably because we still need to monitor them to make sure they're doing the right thing). But imagine self-driving cars with no traffic lights, because the cars can react & communicate fast enough to avoid a collision without any macro-scale signaling. Manufacturing processes where molten metal is shaped directly into whatever shape desired, where computers do real-time calculations of the effect of gravity & cooling rate on the position of the material. Airliners that never land and can take on passengers anywhere, because passengers ascend in a personal drone that mates with the mothership under computer control.
Unfortunately CVaaS isn't really suitable for this, because the network delays transmitting the data to a datacenter will outweigh any speed benefits of computerizing it. But I could see a big market for services that let you train a model in the cloud at high-speed, and then download the computed model for execution on a local GPU or TPU.
