Why are so many people calling Elon Musk by his first name, like he's their buddy or neighbor? This reminds me when Steve Jobs had passed away, many people were walking the streets with candles and cards in memoriam of "Steve". How come?
Nobody can just say Steve or Bill without confusing people
When nobody knows you, they use the complete name, Elon Musk.
When you're famous, they drop the given name, you're Musk.
When you're ultrafamous, they only use the given name, now you're Elon.
