Another trend towards lower-power and lower-fidelity in AI-driven computer recognition systems. Last week, IBM announced it was developing better 8-bit AI hardware as an alternative to 16- and 32-bit systems, speeding computations and reducing hardware demands.

I guess once the human aspect is removed, the sensor and processing systems can be tailored for the computer aspect of recognition tasks, which isn't necessarily as powerful or high-definition as we expect.
