A car built early in the 20th century, and a car built now, about 100 years later, isn't an extremely radical shift; sure there have been changes, but the concept is the same, and all we have done is improve/build over, right? Hold that thought.
A prokaryote (Eubacteria) at the dawn of life, the Archean era of Precambrian time, is, in fact, the same concept as a multicellular organism such as the relatively recent Hydra; it's the same concept just improved or built over.
Now forget the car analogy, and move to AI (artificially intelligent) creatures. A simple electronic robot on wheels hits an obstruction and "learns" that it mustn't do that again. It stores this information and now has an updated map of its immediate area. A century from now, AI may look radically different, but the concept will still be the same, only improved/built over.
Of course these improvements can be drastic as well. The discovery of semi-conductors and the theoretical discovery of commercially viable superconductors in the future, could, if brought down (or up) to "human" scale, correspond with the drastic change in the way organisms reproduced, from asexual reproduction to sexual reproduction. Meaning the recent development in robotics allowing two similar robots to exchange the information that each has gained, which is what mating is at its most basic level, if conjoined maybe with the power of superconductors, just might be an equivalent drastic change.
What am i getting at? You'll see.
I remember reading about this in HG Wells' The Time Machine, and I'll use that analogy here. Imagine if there were 2-dimensional creatures, let's call them the "flatties". Now, these creatures have absolutely no concept of height but, if they had complex brains like ours, they could theorize about the possibility of other dimensions.
