Why are stairs used more than slopes?

Question

Stairs are harder to walk, and higher risk of injury than slopes (imagine falling from stairs versus falling from slope).

So why aren’t slopes used more commonly in buildings?

Even stairs-shaped escalators are more common than slope-shaped escalators.

**Edit:** By “slopes”, I mean “ramps”. Pardon my English.

Answer 1

Slopes built with the same steepness as an average staircase will be too steep to climb. For a slope to be climbable it has to be shallow, which means it’ll be very long which 1) isn’t always possible to engineer, and 2) may take longer to walk
