I am soooo old that when I started my first professional job we used to do project cost estimates using "spreadsheets". However, these were paper and pencil affairs done with large graph paper and pocket calculators. The big problem with these was if the boss said "what if we change the estimate of hours needed for these three tasks...how does that change our bottom line (lots of smudgy erasures on those spreadsheets, and lots of errors too). Computer spreadsheet programs hadn't been invented yet. I bet few or you youngsters here realized that the term "spreadsheet" long preceded the advent of the PC.
"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan
