Scientific predictions that did not come true
Futures that did not come to pass

Yes, even the wise make mistakes. Here are a few scientific predictions that were wrong. Or were they?
We should be living on Mars by now

“The first man will set foot on Mars in 2024," said Elon Musk in 2016. Spoiler: In 2025 we are still sending drones with cheesy names like Perseverance.
Flying cars

A prediction that has not yet come true. In 2016, Uber introduced its flying taxi project, Elevate, and aimed to have it up and running by 2023. But...
Paper will sisappear

Computer scientist and architect Nicholas Negroponte specialized in predictions supposedly based on scientific projections. He claimed that books and newspapers in paper form would disappear by 2015. He nearly got it right with newspapers, but physical books are still enjoying good health.
5G and mutant tomatoes

In 2018, a group of Russian researchers claimed that 5G would alter plant DNA. There are still no tomatoes with legs or homicidal lettuces.
The end of oil… in 2010

In 2002, numerous reputable outlets published predictions about the “peak oil” in 2010, talking about the last peak in oil production before it would run out completely. And yet, massive reserves still sit underground, reserves that we really should leave because fossil fuels are poison to our planet.
The vaccine that would turn us into antennas

Robert F. Kennedy Jr. is now the powerful head of American medicine, appointed Secretary of State for Health by Trump. But before, he was an activist against conventional medicine, moving in circles that believed COVID vaccines contained “nanotechnology controlled by Bill Gates.”
The Himalayan glaciers, gone… by 2035?

A 2007 IPCC report predicted that the Himalayan glaciers would disappear by 2035. Later, the scientists who conducted the study corrected it, claiming that perhaps it wouldn't be so soon. But let’s not be complacent: climate change is real, and if we continue this way, we will end up melting all the ice on the planet.
