Elon Musk Criticizes 'PhD' on Social Media as Arrogant

Tesla CEO Elon Musk doesn’t like it when people put this one word on their social media profiles. He believes that people who put “PhD” in their social media name are a sure sign of arrogance.

Musk said this in response to criticism he faced over a previous tweet that sparked this debate on social media. It all started when Musk recently took to microblogging site X (formerly Twitter) to write: “This false nomenclature of ‘researcher’ and ‘engineer’, which is a thinly-masked way of describing a two-tier engineering system, is being deleted from @xAl today. There are only engineers. Researcher is a relic term from academia.”

Sharing a screenshot of Musk’s tweet, Parmita Mishra, CEO of AI biotechnology startup Precisgenetics, wrote: “This is the dumbest thing I’ve ever seen in my life”.

Replying to Mishra’s post, Tanishq Mathew Abraham, CEO of AI healthcare startup Sophont (who also holds a PhD in his X profile name), said: “This sort of mindset is probably why xAI failed to catch up to other frontier labs. If he [Musk] wants to make SpaceXAI into a frontier lab, hope he changes his mindset. Though being a cloud provider is probably something they can easily excel in anyway lol (Colossus is impressive!.”

Replying to Abraham, Musk wrote, “Putting ‘PhD’ in your social media name is a sure sign of a pompous retard.”

The debate didn’t stop there as another X user named Jawwwn added Musk’s comments to an old video of Palantir CEO Alex Karp in an interview. In the interview, Karp can be seen saying, “I went to Frankfurt and got a PhD in Neoclassical Social Philosophy, which is a fancy way of saying—a quick path to being unemployed.”

Palantir CEO Alex Karp wants people to stop mocking Elon Musk’s bigger ambitions

Last month, Karp Alex defended Elon Musk against criticism over his focus on long-term ideas such as space exploration, AI, and humanity’s future. In a 22-point manifesto shared by Palantir Technologies, Karp argued that society often mocks billionaires who engage with broader cultural or technological visions rather than focusing solely on wealth creation. He wrote, "The culture almost snickers at Musk's interest in grand narrative...”

The post, which has gained over 30 million views on X, has sparked discussion around the influence of tech leaders beyond business.
