Why are technical machines called technical machines?

Question

They don't seem very technical to me. Please don't question my curiosity.

Comments

It could be that it's because they hold battle techniques.

So hidden machines hold battle hiddens?

No. HMs hold hidden techniques used to maneuver in the overworld.

I guess it's because they are technically made to just magically learn moves or its because they teach techniques as Shady Sceptile said.

Answer 1

Taken from the online dictionary:
Technical (adjective)~ relating to a particular subject, art, or craft, or its techniques.
Moves can also be described as a Pokemon's techniques, correct?
Since TM's teach moves, they're technical.
And they're machines.
There you have it, sumwun. My idea behind the name of TMs.
