I came across this great quote from Sir Micheal Atiyah. It is in Barry Mazur’s foreword to Tobias Dantzig’s book Number: the language of science (the 2005 reprinting of the 1930 classic).
Algebra is the offer made by the devil to the mathematician. The devil says: I will give you this powerful machine, it will answer any question you like. All you need to do is give me your soul: give up geometry and you will have this marvelous machine. —Sir Michael Atiyah, 2002
