Answer:
Elon Musk
Explanation:
As of this year the richest person in the world is Elon Musk. He is the CEO and founder of Tesla, SpaceX, Neuralink, and The Boring Company. He has a net worth of $197 Billion Dollars which recently surpassed the CEO of Amazon's net worth which was $182 Billion Dollars. The number one richest person in the world usually changes every couple of years due to good/bad investments and/or changes in the world economy.

"Tragic," may work, depending if the questions is multiple choice or not.
