I thought the U2 was replaced by the SR-71 Blackbird, which has been also retired. I don’t know if we replaced the SR-71 or we’re depending on satellites only.

Are we still flying the much older U2? Why retire the SR-71 and still fly its predecessor?

The U2 is still useful and MUCH cheaper to operate. SR-71missions are just this side of a space shot.

Could be cheaper that way, the SR-71 took a lot of maintenance and preparation for each flight, I'm sure the U2 is easier to run and maintain. That's my guess.
