Hehe, you one upped me for sure :)
We are joking around of course, but sometimes interesting innovation comes from weird ponderings.
I have an experimental cloud phone that has no CPU and uses an FPGA to directly transfer data from a VM in the cloud to the screen. It works, even on 4G but better on 5G. Also, I have been experimenting with transparent OLED.
My dream would be a device completely cloud based, and hence, unlimited processing and storage. The back of the transparent display would be optical sensors and it would use computational imaging in the cloud, no lenses needed. The audio who knows, MEMS I suppose.
I think the technology exists; would anyone want such a thing? Who knows, we have seen things like that in sci-fi movies of course.
