I agree, and as ARM becomes more standardized (less janky), it will be a great platform for deploying these things. I just got a few rockchip 3588 sbcs and in spite of the minimal support for them, they are very impressive. Building out a proper xarm standard will be huge for lower power devices that can take a lot of need away from local big power sinks.
The future is still bright even with NUC going away.
