* Those who refuse to use a calculator over a slide-rule will fall behind because they won't be able to produce as much * Those who refuse to use a spreadsheet over calculator and paper will fall behind because they won't be able to produce as much * Those who refuse to use a truck over horse drawn wagon will fall behind because they won't be able to carry as much Seems pretty common sense to me, rathern than aggressive.
