en.wikipedia.org/wiki/Elon_Musk

Canadian government materials explaining the history of the Citizenship Act say that under the 1947 law in force when Elon Musk was born in 1971, a Canadian woman who married a foreign national could not pass Canadian citizenship to children born abroad. The Department of Justice specifically uses this as an example of the old sex-based rule, and notes that the 2009 amendments later restored citizenship status to many first-generation children affected by that exclusion.

So, even though Musk's mother was born in Canada, that did not make him a Canadian citizen from birth under the law that applied in 1971. The article may still be right that Musk is a Canadian citizen now, but the phrase "from birth" is not supported by the law then in force.

Listing Musk's Canadian citizenship as "since 1971" says he was a Canadian citizen from birth. But the Canadian government has explained that, under the 1947 citizenship law still in force in 1971, a Canadian woman married to a foreign national could not pass citizenship to children born abroad.

Because the article itself states Musk was born in South Africa to a Canadian-born mother and South African father, the law contradicts the infobox date. Whatever later path gave him Canadian citizenship, the available legal history does not support "since 1971."

The infobox says Musk assumed office as SpaceX CEO on March 14, 2002. But official SpaceX offering materials distinguish between two different dates:

• March 14, 2002: the date SpaceX was founded and incorporated.
• May 2002: Musk's appointment date as CEO.

So the date in the infobox is using the company's incorporation date where it should be using Musk's CEO appointment date.

This sentence gives the wrong founding month for SpaceX. Official SpaceX offering materials filed with the SEC state that SpaceX was founded and incorporated on March 14, 2002.

Other official SpaceX materials separately list Musk's appointment date as CEO as May 2002, which likely explains the mix-up. But the company's founding date and Musk's CEO appointment date are not the same thing, so "founded SpaceX in May 2002" is inaccurate.
