Question Average Mean Deviation VS. Standard Deviation

Average Mean Deviation, to me, has a much more intuitive meaning than Standard Deviation. Truthfully, I'm not even sure why we use Standard Deviation. I suppose that's where my statistics class failed me. Anyway, I have a few questions:
  1. Why isn't average mean deviation taught in elementary statistics classes?
  2. Which should I be using for my own personal projects?
  3. What would, for example, a confidence interval look like if I were to use Average Mean Deviation instead of Standard Deviation to obtain its formula?

Standard deviation gives more weight to larger errors.

When you are updating data and getting deviations along the way, average mean deviation is more cumbersome than standard deviation.
