That doesn't necessarily follow. Just because you can imagine something doesn't make you capable of actually creating that thing.

[Silurian]

Automatic tuners.

You would have a dial with alternate tuning settings, turn the dial and the guitar automatically adjusts the tuners. I'm surprised it hasn't been done already, you could sell millions of guitars with this feature.

Auto-string changer.
Just put a packet of new strings on it and, presto, only a minute later your acoustic has new strings, perfectly wound and cut at the peg-head!

[M Sarad]

Built in cup holder.

[Brucebubs]

Instant talent ... just add beer.

[Jack Orion]

A small (ie not noticeable by the crowd) headstock tuner that was accurate with a good display and that had a built in rechargeable battery...

All the good ones are big, and I hate using all these little watch batteries up...

[musicman1951]

A one handed spring capo that had the perfect intonation of a yolk capo.

[Dut4907]

A guitar with interchangeable backs.

[RP]

A guitar rental library so that we could freely audition/exchange guitars with minimal financial outlay. We could call it The GAS House......

The technology is very close

A guitar case with a button on that changed your strings for you when you put your guitar in it (I hate changing strings).

A capo that would magically change the tuning of individual strings when put on.

A recording device that doesn't make you nervous about every note you play when the red light goes on Lol

That's been done, in a couple of different ways:

retractable human nails, so I can move from nylon to steel string and be content.

D'Addario Micro headstock tuner. This is all you see from the front:



And the display is where only you can see it:



Alternatively they have a soundhole version:




Kinda wish that little tab was made of clear plastic instead of being a black thumbnail-shaped blotch though.

Regarding the batteries, they'll last longer if you get good ones. Try Renata brand:
