ELI5:Why manual car drivers change gear at a very high rpm (6k+ rpm typically), while automatic cars shift up at a rather low rpm (below 4k)

Manual car drivers can change gears whenever they want, but if they change at a high RPM, it is because they want to accelerate as fast as possible, because peak power is usually produced towards the top of the RPM range.
