I don't know if Elon Musk is another Bernie Madoff or a modern day Steve Jobs. Several months ago Jim Chanos, the celebrated short seller, appeared on CNBC discussing Musk and the "irrational" price of Tesla's stock. (Since his appearance, Tesla's stock has gone up another 50 percent or maybe even doubled - I don't know ...) The discussion, as I recall, was centered around the topic of corporate fraud and "warning signs" investors should watch for.)
In specifically discussing Tesla, Mr. Chanos pointed to a book, (i.e. "The Seven Signs of Ethical Collapse"), by Marianne M. Jennings.

Mr. Chanos asserted that Tesla (and Mr. Musk) match all seven of the warning signs Ms. Jennings details in her book. I suppose it's possible (maybe even likely) that notorious short seller Chanos was bad mouthing Tesla (and Mr. Musk) because he has (or had) a large short position in Tesla stock. OTOH, if Tesla (and Mr. Musk) do eventually crash and burn, Mr. Chanos will be among the first on CNBC saying "I told you so!"
Charlie Munger, Warren Buffett's sidekick, has also expressed reservations about Elon Musk. If I recall correctly, (somebody please fact check me), Mr. Munger acknowledged that Musk has accomplished some great things, but he [Munger] thought it was possible it could all be built on a house of cards. (I'm paraphrasing a bit.) The general gist of Mr. Munger's comments was that he didn't fully understand how Elon Musk was making all these good things happen. If Charlie Munger is confused, what are mere mortals (like us) to make of Elon Musk?
I can guarantee one thing. If I take a long position in Tesla, the stock will immediately crash. Every stock I have bought immediately tanked - which explains why I was always in the running for the Wall Street equivalent of the Heisman Trophy for "Worst Investor of the Year" award. My stock picks were closely monitored by short sellers looking for a quick score.
