Like all advancing technologies, costs will go down. By The Numbers Let’s start with an analogy.

(KB is a Kilobyte, or a thousand ‘bytes’ of digital data, a term now rarely used.) Today we typically use either MB (Megabyte, a million bytes) or GB (Gigabyte, a billion bytes). Lately we’ve even been breaking out the TB (Terabyte, a trillion bytes) and, for the big data centers, PB (Petabyte, a quadrillion bytes) and beyond. We humans love our big-number prefixes. When it comes to the systems used on A...

Animals became an option somewhere along the way, manual tools and techniques added to our abilities, however humanity’s extreme tech curve didn’t begin until individuals were able to easily command energy well beyond their own two hands. Once we moved past that barrier, everything took off. Global power underpins our space program and a...
