I enjoy lifting weights at my home, with no one around. I do it to make sure I don't have to buy new pants. Sports are a good way to tear a ACL.

What will "religion" look like in the next 100-300 years?

This comes up in the new Edge discussion between Yuval Noah Harari and Daniel Kahneman;

In terms of history, the events in Middle East, of ISIS and all of that, is just a speed bump on history's highway. The Middle East is not very important. Silicon Valley is much more important. It's the world of the 21st century ... I'm not speaking only about technology.

In terms of ideas, in terms of religions, the most interesting place today in the world is Silicon Valley, not the Middle East. This is where people like Ray Kurzweil, are creating new religions. These are the religions that will take over the world, not the ones coming out of Syria and Iraq and Nigeria.

The film Prometheus, for example, intrigued me by showing a single woman, an archaeologist character named Elizabeth Shaw (played by the Swedish actress Noomi Rapace), who wears a cross and professes her christian faith at a time when christianity has gone into decline, so that christian believers have become relatively uncommon. Yet she sleeps with a man on the space ship, showing that she practices a liberal morality by traditional christian standards. Does this show where "christianity" could go during its long twilight in the "Jesus who?" age?

BTW, I like tweaking unsophisticated christians who believe in this "end times" nonsense by saying, hey, I believe in the rapture, too: I can see that christians have already started to disappear.
