I started classical piano lessons in kindergarten.
My teacher had a metronome that ran continuoulsy.
My next teacher taught ragtime. She had a metronome that ran continuously.
Started trumpet in the 3rd grade. All my teachers used metronomes.
Played bass with my dad at the age of 10 on gigs.
He played a Baldwin B210 organ (late '60s and early '70s) and our drummer was a machine.
Every studio I've ever worked in had clicks. Period.

That being said, it's time for levitee
Q. What's the difference between a drummer and a mutual fund?

Enough bashing drummers:
Q. What is perfect pitch?
A. When you chuck the accordian in the dumpster, and it lands right on the banjo.
Q. Which is bigger, a viola or a violin?
A. They're the same size, but the violin looks smaller because the violin players have bigger heads.
Q. Why does a banjo player leave his fingerpicks on the dash of his car?
A. So that he can park in the handicapped zone.
Three notes walk into a bar, a "D", an "F", and an "A".
The bartender looks at them and says, "Sorry guys, I can't serve minors."
So the "F" leaves, and the "D" and the "A" have a 5th between them.
Four notes walk into a bar, a "C", an "Eb", an "F#", and an "A".
The bartender looks at them and says, "Sorry guys, I can't serve Diminished 6ths."
The very best drummers can and do play to clicks. It's required.
