Musk suggested that people over 70 should not be allowed to run for political office.
The founder of the two companies said on Thursday that he would like to set an age limit for political office.
The current president, Joe Biden, and his predecessor, Donald Trump, are both over the age of 70. The senator is 80 years old.
In response to the demand that wealthy Americans pay their fair share, Musk said that he was forgetting that he was still alive.
Musk offered to sell more of his stock if the user would stop making jokes about the age of the person.
Musk responded to the criticism of his wealth by saying he would use it to help humankind. Musk said he was accumulating resources to make life multiplanetary and extend the light of consciousness to the stars.
Older lawmakers are a point of debate. The US does not have an upper age limit for people running for president.
He would have been one of the oldest presidents ever on Inauguration Day if he had been successful in his presidential campaign.
On the day after Biden formally entered the 2020 Democratic presidential primary field, Trump joked that he was a young, vibrant man.
27% of Democratic voters said that candidates shouldn't attack their rivals because they're too old.
