Apparently (according to a carpenter friend) - if the carpenter uses a hammer on a modern build it means something has gone wrong - they're normally using nailguns or similar to put things together - hammers are to bash them back apart again or knock them into alignment if they weren't done right the first time.

Hammers can also be used in awkward to reach places that a nail gun can't get to. Also, structural timber is very rarely straight or true. Knocking things into alignment is a very common part of framing, and hammers can achieve sub-millimetre accuracy with gentle tapping.

Yes, nail guns are awesome, but hammers are very useful tools.

I've done some work as a builders labourer. Admittedly ~18 years ago.

Nail Guns are awesome. Pneumatic, butane/battery and powder actuated all have their place and were heavily used. Always had a hammer on my belt though.

In particular, it's hard to use a nail gun to fasten a plate, hanger or bracket.

And to bring it back to the original poster - barely a day goes by that you don't need a ~hammer~ ... version control history.

LOL, yes nail guns are the more efficient tool these days, however I bet these carpenters still have a hammer on their tool belt and use it at least once a day.
