Elon Musk is no stranger to bold predictions. Whether it’s colonizing Mars, launching fully autonomous cars, or revolutionizing brain-computer interfaces, his visions have captivated the world. But not every forecast has come to fruition—at least not yet.
Some of his most ambitious promises remain just out of reach, delayed by technological hurdles, regulatory roadblocks, or sheer complexity. Here, we take a look at ten major Musk predictions that, as of 2025, are still waiting to become reality.
10. Full Self-Driving Tesla Cars by 2017
Elon Musk confidently predicted in 2016 that Tesla would achieve full self-driving capability by 2017. Despite numerous promises and deadline extensions, Tesla has yet to deliver true autonomous driving as of 2025. The company’s “Full Self-Driving” feature still requires active driver supervision, falling short of Musk’s ambitious timeline.
9. One Million Robotaxis on the Road by 2020
In 2019, Musk confidently predicted Tesla would have over a million autonomous robotaxis operating by 2020. This ambitious goal was not achieved, and as of 2025, Tesla has yet to deploy a fully autonomous robotaxi fleet. The promise of widespread driverless taxis remains unfulfilled, highlighting the challenges in developing and implementing self-driving technology at scale.
8. Hyperloop Operational by 2020
Musk’s ambitious prediction of a functioning Hyperloop by 2020 fell short. Despite initial excitement, technical challenges and funding issues have significantly delayed progress. As of 2025, no commercial Hyperloop system is operational, with most projects still in testing phases or abandoned entirely.
7. Mars Colony by 2024
Elon Musk’s ambitious prediction of establishing a Mars colony by 2024 proved overly optimistic. As of 2025, no human has set foot on Mars, let alone established a permanent settlement. SpaceX’s Starship, crucial for Mars missions, is still in development, with crewed flights to Mars now projected for 2028 at the earliest.
6. Neuralink Human Trials by 2020
Musk’s 2019 prediction of Neuralink human trials by 2020 was off by years. The first human trial didn’t begin until 2024, with only three patients implanted by early 2025. While progress is being made, Musk’s timeline was overly optimistic, as is often the case with his predictions.
5. Solar Roof Tiles Widely Available by 2017
Musk announced Tesla’s solar roof tiles in 2016, promising widespread availability by 2017. However, production delays and technical challenges pushed the launch back significantly. As of 2025, solar roof installations remain limited, with high costs and long wait times still hindering mass adoption.
4. Tesla Semi Truck Production in 2019
Elon Musk’s 2017 promise of Tesla Semi production starting in 2019 fell flat. Despite the initial hype, the electric truck faced significant delays. As of 2025, Tesla is still working towards full-scale production, with plans to begin manufacturing at their Nevada Gigafactory in 2026, aiming for an eventual capacity of 50,000 units annually.

3. Cybertruck Deliveries in 2021
Musk confidently predicted Tesla would deliver Cybertrucks by late 2021. However, production delays pushed the timeline significantly. The first Cybertrucks weren’t delivered until November 2023, two years later than initially promised. This miscalculation highlights the challenges of bringing innovative vehicles to market on schedule.

2. SpaceX Starship Reaching Orbit in 2022
Musk confidently predicted in February 2022 that Starship would reach orbit that year, stating, “I feel, at this point, highly confident that we’ll get to orbit this year.” However, Starship’s first orbital flight attempt didn’t occur until April 2023, and it failed to reach orbit, exploding minutes after launch.

1. Tesla Model 3 Production Targets in 2017
In May 2016, Musk ambitiously predicted Tesla would produce 100,000 to 200,000 Model 3s during the second half of 2017. Reality fell far short, with Tesla manufacturing just 2,685 Model 3 vehicles in 2017. This significant miss highlighted the challenges of scaling up production for Tesla’s first mass-market electric vehicle.
