It's easy to mount one's high horse and blame the students for this state of affairs. But they didn't create the present culture of consumption. (It was largely my own generation, that of the Sixties, that let the counterculture search for pleasure devolve into a quest for commodities.) And they weren't the ones responsible, when they were six and seven and eight years old, for unplugging the TV set from time to time or for hauling off and kicking a hole through it. It's my generation of parents who sheltered these students, kept them away from the hard knocks of everyday life, making them cautious and overfragile, who demanded that their teachers, from grade school on, flatter them endlessly so that the kids are shocked if their college profs don't reflexively suck up to them.
When Armstrong again looked outside, he saw that the computer's landing target was in a boulder-strewn area just north and east of a 300-meter (980 ft) diameter crater (later determined to be West crater , named for its location in the western part of the originally planned landing ellipse). Armstrong took semi-automatic control  and, with Aldrin calling out altitude and velocity data, landed at 20:17:40 UTC on Sunday July 20 with about 25 seconds of fuel left.
