Sure, you could put a 3 Ghz CPU in your microwave oven, or vacuum cleaner, or whatever. But now, your power consumption is significantly higher than your competitor's product. And you may now have problems with heat dissipation. And your BOM cost is a few dollars more. So yeah, in some kind of theoretical world with unlimited resources, performance is no longer a concern. But in the real world, it very much is.
The other dimension to performance is realtime guarantees, which Minix can't provide. So overall, I think AT is just whistling in the dark here.

To do what? Un-compress and display a video recipe from Youtube? Please be serious. I'm talking "Mega"/cheap and you answer "Giga"; you are off-topic.
Do you have any idea what is the cost of 1 MIPS in the low range nowadays? Answer: totally negligible compared to the rest of the SoC. And not just in dollars but in terms of power and real estate just as well.
Backtracking: yes, the extra performance cost of a micro-kernel would not make any difference to your microwave oven.

Do people really run microkernels on 8 or 16 bit microcontrollers?

I don't know, but they are all rapidly in the process of getting 32-bit microcontrollers (which is pretty remarkable but seems to be the way the world is headed).
