I'd have to dispute that--ATF change intervals are about the same as clutch change intervals (disregarding the "lifetime ATF" crap that manufacturers peddle) but cost far less, and otherwise automatic transmissions today last the lifetime of the car.
if so inclined, you can repair or replace your own clutch (as a hobbyist or someone who is mechanically inclined), but doing the same to a hydraulic-based automatic transmission or a CVT is a tall order unless you are professionally trained.
ATF change - 30,000 miles.
Clutch service - maybe 300,000 miles if your car body lasts that long before rusting to hell.
That's if you know how to drive.
