The easy part is building it. The hard part starts after it works.

I’m Alexander Titus. I’ve spent more than a decade building and governing AI and biotech, and written five novels about where they lead. One question runs through all of it: once we can change almost anything, who gets to decide what we become?

03The writing

Fiction is where I run the experiment.

Some questions get too big for an essay. A memo warns you about a future; a novel puts you inside it. With Sean Platt, I write the experiments reality is too small to run: the futures I’m trying to prevent, and a few I’m rooting for.

Away from the desk I go looking for the edge of what I can do, on foot, on a bike, up high. Three thousand miles from Alaska to California in 2014, in tandem, among others. The reason is the same as the work: an idea has to survive contact with reality, and the limits other people accept are not yours to inherit.
