Spider-Man · where the technology stands
Climb walls, shoot webs, sense danger early, move with many times a human's strength. Take each ability one at a time and ask how far it has come by 2026, using only real research and products. Surprisingly, wall-climbing and silk are much closer to reality than the films suggest.
Real today Partly In the lab Not soon Four grades, based only on what real products and research can support
In the films: Stick to a building with bare hands and climb.
In 2014 a Stanford team fitted gecko-inspired dry-adhesive pads to a climber's hands and a ~70 kg person scaled a vertical glass wall. The same year DARPA's Z-Man program had a person of nearly 100 kg climb about 8 m of glass. The mechanism is van der Waals force, exactly as in geckos. It wants smooth surfaces like glass or metal; concrete and wet walls remain hard.
In the films: Silk stronger than steel, in bulk.
Artificial spider silk is clothing now. Spiber in Yamagata, Japan ferments spider-silk protein at scale (Brewed Protein), used in The North Face jackets; Bolt Threads (US) and AMSilk (Germany) do similar work. 'Stronger than steel for its thickness' describes natural dragline silk; mass-produced fibre does not yet match it in toughness.

In the films: Liquid turns to thread in mid-air and hauls objects in.
In 2024 Tufts University's Silklab showed a silk-protein solution that solidifies into a fibre as it leaves a needle and can grab and lift distant objects, up to 80 times its own weight — a genuine web-shooter proof of concept. The threads are thin; nothing near a strength or volume a person could swing from.

In the films: Feel danger from an unseen direction before it arrives.
The 'SpiderSense' suit from the University of Illinois Chicago (2013) used ultrasonic sensors to detect nearby objects and pressed on the skin to signal direction; blindfolded wearers could point at approaching people. All-round sensing on self-driving cars and drones is the same idea. It is awareness of unseen directions, not precognition.

In the films: Cross a city on threads like a pendulum.
No one swings on threads, but people do fly between buildings on wingsuits and paragliders. Using them routinely in cities is a legal and safety question, not a technical one.

In the films: Stop a truck with one hand.
Gene edits that boost muscle (myostatin inhibition) have produced 'double-muscled' mice and cattle, but in humans they are at the stage of therapeutic trials with limited effect. For tools, exoskeletons are the realistic route (Iron Man page).

In the films: A broken bone mended overnight.
Regenerative medicine has reached the clinic for skin, cartilage and some organs, but healing 'in hours' is bounded by how fast cells divide, and no drug changes that by orders of magnitude. Salamander regeneration research is still chasing the principle.

In the films: One bite from a radioactive spider makes a superhuman.
Radiation only damages DNA; it adds no chosen ability. The technology for adding one on purpose is genome editing such as CRISPR, but there is no way to rewrite every cell of an adult body, and germline editing is halted by ethics and law. Real cases are listed on GERMLINE.

In the films: Dodge a bullet.
Nerve conduction tops out around 100 m/s, a physical and physiological ceiling. Training speeds up prediction, not the reaction itself, and never by orders of magnitude.

Spider-Man is a hero whose body was rewritten; Iron Man is a hero who wears tools. So the scorecards come out reversed. The tool side (silk, adhesion, sensors) keeps turning real, while the body side (strength, healing, reflexes) has barely moved. Editing human genes is covered, cases only, on GERMLINE.
