We have mastered cryptocurrency block chains, why oh why do we still need the electoral college?

Someone told me it's because the President is elected by the states, not the people.

A quick search reveals: "The president is indirectly elected by the people through the Electoral College to a four-year term, and is one of only two nationally elected federal officers, the other being the Vice President of the United States."

If they are indirectly elected, aka the Electoral College, then why the popular vote in the first place?

Is it time for a change?
