The first computer programmer was Ada Lovelace in the 19th century.
No, she wasn't programming on a MacBook Air — it was the 1800s — but she became a colleague of Charles Babbage, who had designed a calculating machine and was working on an even more sophisticated one. In working with Babbage and fellow mathematician Luigi Menabrea, Lovelace discovered that these machines could carry out complex sequences of mathematical operations. The example she wrote to demonstrate her idea is regarded as the first ever computer program.
If we used hovercraft instead of wheeled vehicles, we would not have to waste tens of billions every year building and maintaining roads; we would just need a few guardrails here and there to protect landscaping. And no need for spreading salt and brine to melt road ice because the hovercraft would basically treat all surfaces the same, whether lawn or snow or water it would make little difference.
Also, damage from accidents would be negligible, so insurance rates would be minimal.
Not to mention that squashed critters due to tires running over them would be a thing of the past.
So it seems like the Aztecs were ahead of their time.
