Iron Man · where the technology stands
Fly in a suit, power everything from a small reactor in your chest, talk to an AI butler. Take each ability from the films one at a time and ask how far it has come by 2026, using only real products and research. Not a dream list — a line between what you can buy, what is being tested, and what physics resists.
Real today Partly In the lab Not soon Four grades, based only on what real products and research can support
In the films: Lift off on small jets on the arms and back and fly freely.
Gravity Industries' jet suit really flies: two arm-mounted and one back-mounted micro gas turbines, a few minutes of flight, speeds around 100 km/h. It has been trialled for boarding ships with the Royal Navy and for mountain paramedics. Fuel lasts minutes, so it is a short hop, not transport.

In the films: Put on the armour and lift a car.
Full-body powered exoskeletons are products. Sarcos' Guardian XO demonstrated workers handling about 90 kg with ease; Japan's CYBERDYNE HAL is a medical device covered by insurance. The 'strength' lives in factories, care and rehabilitation, on a backpack battery lasting hours.

In the films: An AI butler runs the house, the lab and the fight.
AI assistants that take spoken instructions and do research, code and scheduling are daily life now. This very site is built by talking to a coding agent (how). What is still missing is a body that can physically run the house, and reliability you can leave alone.

In the films: Enemies, maps and suit status overlaid on your view.
The F-35 pilot's helmet fuses camera feeds from around the aircraft so the pilot can 'look through' the floor. Apple Vision Pro and AR glasses head the same way for consumers. The gap to the film is weight, field of view and outdoor legibility.

In the films: Replace a lost arm with a mechanical one.
Open Bionics' 3D-printed myoelectric 'Hero Arm' comes in an officially licensed Iron Man design; children open and close the hand with their own muscle signals. Grip, touch and finger freedom still fall far short of a living hand.

In the films: Think, and the armour moves.
Participants with invasive BCIs such as Neuralink control cursors and games by thought, and there are clinical cases of paralysed people walking an exoskeleton by brain signal. The bandwidth for reflex-speed whole-body control is orders of magnitude away. More at BCI WATCH.

In the films: Armour flows over the body from a chest device (Mark 50).
Shape-changing materials exist in the lab: 4D printing, origami robots, magnetically driven liquid metal. Nothing in materials science points to covering a body in milliseconds with bullet-stopping strength.

In the films: Beams from the hands that knock enemies back and steady flight.
Directed-energy weapons (high-power lasers) are reaching service on ships and vehicles, but power and cooling keep them far from palm-sized. For attitude control, the jet suit's arm turbines are the closest real thing.

In the films: A palm-sized reactor that powers the suit and the house for years.
This is the real wall. Fusion crossed a milestone in 2022 when NIF got more energy out than the lasers put in, and Commonwealth Fusion's SPARC and Helion aim for demonstrations in the late 2020s — but all are building-sized power plants. Portable power tops out at chemical batteries (~250 Wh/kg), under a thousandth of the film. A tiny fusion reactor has no physical roadmap.

In the films: Thin metal that shrugs off tank rounds.
Shear-thickening fluids (D3O and the like) and ultra-high-molecular-weight polyethylene have made light armour better, but 'thin, light and stops everything' runs into conservation of momentum. The energy still goes into the person inside.

Flying, lifting and seeing are already partly for sale. Power is the one wall that has not moved in decades. Take Iron Man apart and most of the parts are engineering; only the chest reactor is a physics problem. So the line to watch on this page is the fusion line.
