Elon Musk is sketching out what he sees as a multi-year turning point for artificial intelligence across his companies.
In a series of posts on X, the Tesla and SpaceX CEO lays out a timeline stretching from humanoid robots to autonomous vehicles and interplanetary expansion.
He first addresses Tesla’s Optimus robot and when it could start reshaping industries.
“It will begin to transform things in 2027, be obvious in 2028 and have a massive impact by 2029.”
In January, Musk said that Optimus could be available for sale to the public by 2027.
Musk has repeatedly described Optimus as a long-term growth engine for Tesla, noting that large-scale deployment of humanoid robots could eventually dwarf the company’s car business.
He then turns to Tesla’s autonomy ambitions.
“Tesla will have the largest fleet of autonomous vehicles as far into the future as I can imagine.”
The comment reinforces Musk’s long-standing bet that full self-driving technology will give Tesla a structural advantage in ride-hailing and mobility services.
Finally, Musk addresses speculation about SpaceX’s priorities after recent talk of a stronger near-term focus on the Moon.
“To be clear, we are still going to do Mars. I don’t think this change affects the time to a Mars city being self-growing by more than five years, and it might turn out to accelerate Mars.”
Musk has said that building infrastructure closer to Earth could speed up iteration cycles and ultimately support a self-sustaining city on Mars. He also said that SpaceX could achieve a self-growing city on the Moon in less than 10 years.
Taken together, the posts outline a broader AI-driven roadmap: humanoid robots scaling by the late 2020s, a dominant autonomous vehicle fleet and continued progress toward a self-growing city beyond Earth.
