Horses are faster than humans. I don't see them suddenly taking over based on that fact alone.
The ones I see deployed in construction do stuff like drilling holes in hard to reach places, or laying bricks. None of them look like people, though. Much like the typical household dishwasher hasn't been named Alice or Doris for the past 50+ years, but rather Bosch or Samsung and doesn't use actual hands.
But yeah, humanoid robots do look cool and many movies and books told us to be fearful of them.
