But why would I want to use a screwdriver when I could use my power drill? Like sure, the screwdriver works, but it's more effort and slower...

Actually there's lots of times I want to use my hand driven driver rather than a motorized one.

I agree with the other comment mentioning analogies have their limits. Are we going to pick them apart just so we can avoid listening? Communication is lossy. Are we having a conversation or just trying to win a game of our own design?

I add that because how I interpreted taeric's point of a drill and a driver is just a variation of "apples and oranges." You can concentrate on how they're both round fruit or you can recognize there's differences. I mean walk into any machine shop or go to your uncle that likes to make things and have them explain why they have so many wrenches of the same size but in different styles. Often the subtle differences are the most important part. Hell, how many people even know what those numbers do on the power drill? Making use of them really ups your game. Same with adjusting the power level on your microwave. Yet I rarely see people use these things which are highly effective and help avoid many common mistakes.

Analogies have their limits. That being said, there is always a learning curve. Imagine a situation you want your 5 year old to assist you, but you don't want to teach them how to safely use a power drill.

Sometimes torque is a bad thing.

I see you've never seen or dealt with a head blown out of a fastener. A drill has basically no feel, and things escalate quickly especially for marginal fasteners.
