The future was never like this!
my experience.
The term "valve" is more of a function thing by analogy
with a valve controlling the flow of liquid, a thermionic valve is used
I beleive the origin of the term 'valve' goes back to the diode, by
analogy with the one-way valve on a tyre or something like that.
