Stuff AI CAN'T Do

Can AI create synthetic red blood cells that operate independently of the human heart by using onboard ai to regulate oxygen delivery and blood pressure ?

What do you think?

Lab-grown red blood cells exist, but fully autonomous delivery systems remain aspirational. If realized, this could redefine transfusion medicine and human physiology. Can AI replace the circulatory system?


Current artificial red-blood-cell projects rely on micron-scale mechanical pumps driven by external magnetic or ultrasonic fields; no system has yet integrated onboard AI to autonomously regulate oxygen release or blood pressure without a beating heart. Research-grade prototypes demonstrate pulsatile flow and oxygen unloading over minutes in benchtop circuits, but they lack the metabolic sensing, adaptive control, and multi-hour durability needed for independent circulatory support. Because such devices must operate with sub-second latency inside the body, engineers are exploring custom neural-network chips and wireless power links, yet full independence from the heart remains beyond today’s demonstrated capability.
