Encounters with technology day 1

I have been working all week on a small remodel, opening up a closet for the installation of a closet system and media center. I take for granted all the modern tools that all carpenters use. There are the saws that can shave off fractions of an inch off a board, all the air collection additions that allow you to do work in a furnished room with almost not dust, but the tool I certainly could not work without in remodeling is the nail gun. This is funny to me because in class there were a lot of metaphors involving hammers, better hammers etc. The nail gun is the ultimate better hammer its greatest and most important quality being that is can sink a 16p nail into wood with basically no vibration, impossible with a normal hammer and nail. So nearby plaster does not crack, cups do not fall off shelves upstairs. It is really remarkable. There is a price of course, cost of the equipment, complexity of the equipment, and safety. I have twice been injured by my use of a nail gun. I am going to think about what the cost are of technology as the week progresses
