For starters, planes today use many different forms of propulsion such as jet, pulse jet, jump jet, rocket, and propellers. The planes in WWI only used propellers. Also, the amount of technology in the planes has increased a thousand fold. Planes today can take off, fly, and then land themselves, all on auto pilot. Physical pilots are there in case a.) something goes wrong and b.) for the passengers. Tell me you wouldn't be nervous if there was nobody on the plane who could fly it if things got sticky.
