People who are asleep. People who are not actually alive. People who are threatened by those who think.
These people hate the thinker, but their dreary little lives rest directly on the foundation that the thinkers provide. For example, the radical who first looked at fire and thought, "hey, maybe I could use that".... now THAT GUY was a visionary who puts Musk to shame.
Really this type of people are just machines. And they will be the ones machines are easily able to replace.
A predictable machine is more useful to you than an unpredictable human.
