Off-topic/vertical comparison:
Some say that earth was originally populated from another (or other) planets and use the archeological findings of things like the baghdad battery to justify the theory.
The Baghdad Battery is an ancient artifact, a clay jar with a copper cylinder and iron rod, found near Baghdad and dated to the Parthian era (c. 200 BC), that functions as a simple galvanic cell when filled with an acidic liquid like vinegar, producing a small electrical current, possibly for electroplating or other purposes, though its exact use remains debated, with theories ranging from religious rituals to simple storage.

A conceptual parallel that might be drawn is a metaphorical one:
- An OOPart is considered "out of place" in a historical or archaeological context due to a perceived chronological or technological mismatch.
- A domain name can be considered an artifact within the field of digital archaeology and as a cultural indicator of the modern era. While not physical objects like ancient tools, they are human-made digital constructs that provide significant insight into human behavior, technology, and culture at a specific time.
Note: The above just reinforces that there is no cap or limit on a domain names potential registration and that moving forward, in 20 to 50+ years from now, many domains themselves may be considered digital artifacts.
Affordability for mom and pop start-ups is my primary focus on this topic, where newer TLDs are starting to treat domains like brick-n-mortar commercial real-estate, flushing out mom and pops trying to make a living and only welcoming the larger seed funded corporate start-ups.
That's the road it appears to be on anyway. Still lots of affordable domains today, without factoring in the super high premium options.
