So you basically think inventing perpetual motion machines from scratch is another method to get Supergenius? I wouldn't mind that too much.
If that perpetual motion machine could actually have unlimited effect on its environment, sure. For example, inventing a power source and machine to power a bomb which would warp everything in existence with an infinitely powerful explosion (without access to an existing source of infinite energy).
It seems to me like Ant wants Supergenius to refer to a level of intelligence which allows for that person to be unrestricted in the level to which they can manipulate their environment, aka, to an infinite degree.
Even someone with all theoretical knowledge could not create infinite energy, but could theoretically create any amount of energy below that, and so to me it seems like the logical divider where the level of intelligence moves from some higher level of normal intelligence and into a fictional, unfathomable intelligence.
Well, I suppose that "on an at least base-level infinite scale" is better than what we have currently at least, but there were a few other suggestions about clarifications for intelligence feats that do not relate to technological inventions as well, so help with wordings for additions to our current definitions would be very appreciated.
If we use a simpler basis of "infinite" for our definition, it also becomes a lot easier to define outside the terms of technology or science, since we no longer need to hinge ourselves on timelines, dimensions, or anything more abstract.
Some examples:
1.) Reading and comprehending an infinite amount of knowledge, such as the entirety of a magical tome which contains all past, present, and future knowledge.
2.) Creating from scratch the framework of a type of magic which has infinite potential using only existing finite tools and knowledge.
3.) Being intelligent enough to calculate every possibility until the end of time, allowing them to manipulate the universe at this scale indirectly and be perfectly clairvoyant.
4.) Creating any device with infinite output or an infinite structure from finite ingredients.
5.) Calculating and manipulating concepts/laws which affect all of reality with finite ingredients.
I'd suggest something like:
Supergenius: The highest level of non-omniscient intellect, possessed by individuals with unfathomably superhuman intelligence which exceeds finite measure or normal logical limits, being able to comprehend or utilize information on a practically infinite scale.
For example, to reach this level from inventions, these characters should be able to use them to essentially manipulate reality however they wish on at least an infinite universal (High 3-A) scale, or even overpower Tier 1 entities in higher cases. Simply defying the law of physics is very common for Extraordinary Geniuses as well and is not nearly enough to qualify.
This revised definition gets the same point across without explicitly mentioning technology or science, while making it clear that this level of intelligence should be unlimited from a human perspective.
