I was watching a show called "Extreme Engineering" today. This episode discussed building a 1km high pyramid to house 750,000 people. An interesting idea, and possibly not so ridiculous as it might sound at first. But that isn’t what I want to yammer about today.
There seems to be a plethora of ideas for megascale engineering. Everything from gigantic pyramid cities to space elevators to colonies on distant planets. These things used to be the sole province of science fiction and fantasy stories yet now people are seriously considering building just such things. In fact, for much of this stuff, the technology to actually accomplish it does not seem to be so hugely far off.
I don’t know whether this is a testament to human imagination and skill or an example of sheer hubris. Either way, it will certainly make for interesting times to come.
