Lately, I’ve found myself reading more classic science fiction. I went through Asimov’s entire Foundation saga, and am currently reading Clarke’s Odyssey series and his Rama series. The science fiction of old reflected a time of general optimism for space travel and colonisation. One day, we’d escape our cradle, Earth, and settle throughout the galaxy. We may or may not encounter other intelligent life-forms; even Asimov thought humans would be the dominant space-faring species in the Milky Way (but he hinted, at the end of Foundation and Earth, that Andromeda may host a new form of life we’ve yet to encounter).
The main enabler for us to engage in space travel would be technology. As we sailed the seas with ships and aircraft carriers, so too will we travel the stars in advanced starships like the USS Enterprise. At this moment, we’re taking baby steps towards the development of space technology, slowly and clumsily crawling towards that dramatic breakthrough or “revolution” that would propel us into the future. But, Asimov’s dreams of humans establishing a galactic empire tens of thousands of years into the future maybe under attack.
