Can signs become all electronic one day or highways and streets and no more manually created signs?

I think they will be solar powered for night time and visible during the day.

That's a bad idea, because then no signs would work during power failures.

Nope, we still need things like the street name and exit signs(and things like stop/yield signs) to be "manually" created. First off electronic signs cost money to run, where as the sign just hanging is bought and doesn't cost another cent. However a bigger issue is electronics can fail. Imagine having no idea what the exit from an interstate is because it was electronic only and went out.
