Public conveyances and private carriages were once controlled by rack-and-pinion gear sets or by recirculating-ball tackle. Our ancestors trusted those methods, plus rotary-vane pumps, to mechanize transportation. Since they wanted for steer-by-wire systems, their engines were crowded, their streets were strewn with smashed vehicles, and their technicians were well-moneyed.
In contrast, today we have semi-autonomous rides. We can direct our fleets to hover above the ground. We can send our children alone to travel. We can jump among cities at near light speed. It’s a pity, thus, that our technology goes unappreciated just because we lack the corpora to use it.
