Leave it to Neil deGrasse Tyson to casually predict the next 25 years like it’s no biggie. During episode 1904 of the Joe Rogan Experience, the astrophysicist, author, and science celeb offered a bold glimpse into where humanity might be headed in the next 25 years. While flying cars didn’t make the cut (sad face), his projections are closely aligned with today’s advances in science and technology — and some could be closer than we might expect. 

So, who exactly is Tyson, and what does he think the world might look like by 2050? Get in — we’re going exploring.

Who is Neil deGrasse Tyson?

If you’ve ever caught the eye-watering space series, “Cosmos” or heard someone break down the mysteries of the universe without sounding like a textbook — you’ve probably heard of Tyson. Born in New York City, Tyson graduated from the Bronx High School of Science. He later earned his Bachelor of Arts in Physics from Harvard University in 1980 and went on to complete a Masters and Ph. D in Astrophysics from Columbia University in 1989 and 1991, per Britannica. 

Tyson is best known for hosting the celestial TV series, “Cosmos: A Spacetime Odyssey” and his radio program, “StarTalk.” Beyond his obsession with exploding stars, black holes, and dark matter, he gives viewers a grip on what the heck is going on in the cosmos, and what it has to do with us.

Now, for his next trick, Tyson’s turning that cosmic lens toward laying out what he believes is next for humanity.

Mental Illness Will Be Cured

“Neuroscience and our understanding of the human mind will become so advanced that mental illness will be cured, leaving psychologists and psychiatrists without jobs,” Tyson, 66, said during the interview.

The Take Over of Self-Driving Cars

“Self-driving electric vehicles will fully replace all cars and trucks on the road. If you wanna be nostalgic with your fancy combustion engine sports car, you can drive on specially designed tracks,” Tyson explained.

Space Tourism

Tourism for successful people: the world's first space hotel will open as early as 2027.

Built by Above: Space Development, it will host 400 guests and 112 crew members on a rotating structure designed to create gravity similar to the moon.

“The human space program will fully transition to a space industry, supported not by tax dollars, but by tourism,” Tyson said.

It seems that in Tyson’s vision, regular folks will be able to book a trip to orbit. Voyager Station — a space hotel set to open in 2027 — is already in the works, complete with a bar, restaurant, concert hall, gym, and a cinema theatre, per Astronomy.

The Cure for Cancer & Tailored Medicine

“We develop a perfect ani-viral serum and cure cancer. Medicines will tailor to your own DNA, leaving no adverse side effects,” Tyson predicted to Rogan.

We’ll Regrow Limbs and Organs

“We will learn how to regrow lost limbs and failing organs, bringing us up to the level of other regenerating animals on earth, like salamanders, starfish, and lobsters,” the “Cosmos” host stated.

Artificial Intelligence Won’t Become Our Overlords

“Instead of becoming our overlord and enslaving us all, artificial intelligence will be just another helpful feature of the tech infrastructures that serve our daily lives,” Tyson concluded.
