Given unlimited potential, no, it's not. Given our current constraints in terms of energy density and electronics size, yes, it probably is.

In an unlimited potential world, it would be great to have a phone that was like an A0 sheet of paper folded into an A7 or A8 sheet. So you could "unfold" your phone several times to get a display ranging from a standard cell phone up to a meter across display. No more conference room TVs, someone will just unfold their phone and hang it up.

In a far more advanced world, I expect some kind of human-machine interface will crop up. The twist I expect is that I think they'll be genetically engineered, a la CRISPR. Rather than cutting people open and putting metal inside, they'll inject you with a virus or something that leverages your body's existing systems to make your body build that feature itself.

I.e. if you want that human - computer interlink, they give you a virus that causes your body to deposit iron inside your ears in the shape of an antenna and causes the growth of new nerve tissue to convert those into nerve signals to the brain and maybe a new part of the brain that can "decode" the new nerve signals.
