By now, everyone knows that Elon Musk is very much an optimist when it comes to making predictions.

That's the nice way to put it. To be blunt, Musk is a "bullshit artist." He makes promises he can't keep. For example, everyone now is likely very familiar with his infamous 2011 interview with the Wall Street Journal where he said he'd put a man on Mars in 10 years. That was 14 years ago now and we're nowhere near putting anyone on Mars. Years ago, Musk also touted his proposed Hyperloop train system as a way to quickly transport people between cities; that never came to fruition and was likely a ruse to stop other transit projects.

With 2025 nearly over, Mashable decided to revisit his predictions related to this year. Time has run out. What did Musk promise for this year that didn't come to fruition?
