Estimating Technical Progress

Overestimating the potential upside of every new sign of tech progress is as common as downplaying the downsides. It's easy to let our imaginations run wild with how any new development is going to change everything practically overnight. The unforeseen technical roadblocks that inevitably spring up are only one reason for this consistent miscalculation. Human nature is simply out of sync with the nature of technological development. We see progress as linear, a straight line of improvement. ...

The basic idea of this contract is that authors, journalists, musicians...

 Speculation Informed by Science is Not the Same as Fantasy

Our search for life elsewhere is not haphazard or random: our knowledge of physics and chemistry and biology equips us to seek out meaningful information about stars and planets vast distances away and to identify planets that are at least possible candidates as hosts for life. There is much that remains deeply mysterious, and it is not likely that we will ever uncover all the secrets of a universe as vast as ours: but, armed with science, we can at least ask sensible, meaningful questions ab...

 We are Drawn to the Supernatural

WE HAVE, it seems, a fierce attraction for spirits: auras, angels, poltergeists, disembodied souls, out-of-body experiences. Mostly, I think, we are drawn to these things because we intuit—correctly, it turns out—that there must be more to the world than meets the eye. We inherit the spirit world from a time when our ancestors huddled in dark shelters at night and let their imaginations draw up creatures more or less like ourselves although lacking corporeal substance.
