The current hardware might not be, but you could run this on a secondary chip similar in specs to the T2 or Secure Enclave. You could theoretically even have a second battery specifically for this purpose, but that would likely be cost-prohibitive.

The T2 chip is a derivative of the A10. It has similar power requirements to the SOC in modern iPhones.

They could probably use a cut down derivative of the W2 chip used in AirPods with the audio codec etc. removed. I’m guessing phone batteries reach a point where they’re still storing energy but can’t provide enough current to safely boot the whole phone. The BLE chip could sip on the remainder of the battery for a long time.

That sounds reasonable. I had no idea the T2 was that powerful.

It's also the SSD controller, and quite impressive in that regard.

I bet the T3, whenever that arrives, will be a derivative of the A12 or A13, and provide the neural network accelerator to MacOS and CoreML.

This would be excellent. I'm hesitant about the prospect of an ARM based macbook, but having both seems mighty compelling. As a lower power application CPU for light usage, or a full x86 with accelerators / co-processors when needed.
