A public count, kept in the open
How much of a human being can we change on purpose today?
Not in a story, and not someday. Today, with a device, a drug or a procedure that at least one person has actually had. This site keeps count, and watches the one change that would matter most if it came: a direct link between a brain and a machine.

Each part of the figure is one of the seven branches, shaded by the furthest stage any upgrade under it has reached. Click a part to see what is there.

upgrades on the tree have reached a first human.
Counted from the record, not chosen by hand. An upgrade counts once a public record shows that at least one person has had it, whether or not anyone approved.
An upgrade, here, is one specific way of changing a human being on purpose: an implant that gives back some sight, a pill meant to slow ageing, a chip that lets a paralysed person type by thought. Each one is written down with a plain test of what would count as a person having it, the public record that settles that, and a stage: idea only, shown in animals, a first human, in use by doctors, or in wide use. The stage is a fact about what has happened, not a guess about what will. There are no odds on this site. The seven branches are the seven things about a person that can be changed: what they sense, how they move, how they think and remember, how they feel, how long they last, what they pass to their children, and how directly they can be joined to a machine.
The 4 upgrades on the tree today are examples, seeded on 16 October 2026 to show how the record works while the real list is written. Each says so on its page. The counts above will change as the list fills in.

Why keep count
One idea about the future says that as machines get smarter, people keep up by joining with them: better senses, better memory, a direct line from brain to computer. Whether that is happening is a question with an answer, and the answer is a list. This site is that list, kept in the open so that anyone can check an entry, argue with a stage, or add what is missing. The rules for deciding a stage are under how the numbers are worked out, every change is dated in the story so far, and the place to push back is Disagree with something.
