[BRIEF NOTE] On plausible futurology
Dec. 1st, 2010 12:38 pmIn one of his last posts before Acts of Minor Treason transitions to a mostly photoblog, Andrew Barton has a post describing something important about worldbuilding: a scenario about the future needs to be plausible.
This sort of thing applies for all scenarios purporting to predict future events. If you're making a prediction about the future--Europe's going to become Muslim, say--then you have to do your homework to see if the current trends suggest that, and if there's any likelihood of these trends changing abruptly. (No they don't, and no there's much likelihood.) Thinking about triggers for change--like, say, the Annacis Island hyperdensification--is provocative, but you have to think of reasons why. (Extraterritorial alien enclave in the middle of Metro Vancouver, perhaps?)
Originally dominated by farmland, ever since the 1950s its 4.8 square kilometers have been one of Metro Vancouver's industrial centers. I walked across it in order to reach the Alex Fraser Bridge, and I've been in few places quite so odd; on Sunday afternoons, it seems, Annacis Island is dead. There are few sidewalks, only a handful of businesses that aren't industrial, and I would be very surprised if anyone lived there. Obviously, I concluded, it would be a great place to put a thriving cityscape, eighty years hence! Annacis Island, a thriving place of adventure where anything can be had for the right price - boasting the largest concentration of parahumans in the Pacific Northwest! And I could develop it without having to worry about annoying reality.
Population? Hmm... something like sixty thousand seems reasonable with enough density, no?
It wasn't until later that I had an opportunity to do the math - and sure, with sufficient density, Annacis Island could theoretically support a population of sixty thousand - but with a population density of 12,500 per square kilometer, twice that of Hong Kong. In some places this would be believable - but even with the Lower Mainland penned in by mountains on one side, ocean on another, and the United States on still another, there's plenty of room to spread out here - and very little motivation to densify to such a degree without an extremely good reason to do so.
