From the conclusions:
In terms of comparative demonstrated factorisation power, we rank a VIC-20 above an abacus, an abacus above a dog, and a dog above a quantum factorisation physics experiment. Finally, we provided standard evaluation criteria for future claimed quantum factorisations.
With a grain of salt:
The first
real quantum computer built by humans would be created completely different than seen or thought before, basically by coincidence or by mistake.
Mark my words

yeah it will likely be an Issac Newton inventing calculus moment
if it is even possible for a human in a 3d reality to invent that new math needed.
and if it is invent it will appear to be magical or impossible
Our whole existence sometimes appears "magical".
Disregarding the fact that our realm is just one of 10^500 theoretically possible and focusing on Earth.
The more we look at it, it appears more and more special and not average.
Facts:
1. Earth maintained it's surface temperature in a narrow range over 4 billion years despite Sun's luminosity increasing 20-30% over this time frame.
2. There is no other known planet that has tectonic plate movements. Well, we could not study it yet anywhere else, but in our solar system it is the case.
3. Earth was formed by a rare (or very rare) collision of two bodies with a similar mass, causing evaporation of
all initial water and ejection of a lot of material into space where it formed an unusually large and close-by satellite, causing tides (which were tremendous initially). Whatever water is on Earth right now was brought in by comets and asteroids, apparently. Therefore, it is entirely possible that almost all earth size and larger planets are covered with water-they could all be waterworlds. It is also entirely possible that tectonic plates movement was initiated by that initial collision. Some scientists suggest that evolution "needs' tectonic plate movements to produce variations in the climate, which possibly speeds up evolution.
4. Earth is on a roughly circular orbit around the galaxy, minimizing disturbances. Earth is also on a stable orbit around a relatively stable star.
5. Among more than 5000 studied star systems, they did not find a single planet that was within 10% of the Earth mass in a "goldilocks zone" around the G or K type star. Kepler 186F is 10% larger, but belongs to a red dwarf and, therefore, is tidally locked to that star making it less hospital to life (one side is likely burning while another is frozen) plus it receives just 1/3 or the energy in comparison to Earth. Planets larger than earth might be waterworlds or mini-Neptunes. Kepler 1649c is also a larger planet and also tidally linked to its red dwarf star. Trappist-1e-is probably our best "shot", despite it being tidally locked. Alas, no atmosphere there has been detected.

Either that or prior civilizations "evaporated" into other realms (of pure thought or virtual reality?) and don't bother with the current state of matters in the Universe.
