I'm as liberal as they come, I'm very sensitive to disguised racism, but the tweets' entire basis of comparison between Musk and Moses is "both are/were ambitious men and now musk is talking about infrastructure". It's free-association garbage.
The Moses story is fascinating because he accomplished great things that built NYC but was also a horrible person. The tweeter you linked is like, "hey, Musk is trying to accomplish great things, he must be just like Moses".
