*openings
Amazing, we went from how many openings the human body has to an anatomically incorrect human digestive system to a pipe and then to a cup being a disc.
So you mix the words opening and holes as is possible in common language and then proceed to be anal about the term hole in context of topology. While a scholar of topology uses the common word hole to explain the concept of e.g. an annulus or torus to a student it is not a defined term per se.
For the sake of argument I’ll accept your incorrect application of the term hole as in a pipe having only one hole. This would still mean it has at least 2 openings. In the context of OP (human digestive system) an entry point (mouth) and an exit (anus).
BTW - you shall henceforth consume liquids only from platters and are required to use the word berry only in the biological correct sense (e.g.: straw-thingy, black-thingy, rasp-thingy, cucumberry, pumpberry, pinemultifruit, etc. pp. - have fun)
Your capability at projection is astounding.
So you mix the words opening and holes as is possible in common language and then proceed to be anal about the term hole in context of topology. Actually you interepreted openings as holes multiple times. Neither opening nor hole are specific terms in topology though. A scholar of topology uses the common word hole to explain the concept of e.g. an annulus or torus to a student. You probably stumbled across this, partly understood it and decided to use it to fake intellect - and failed. From then on it just got worse.
While AI/LLMs have their issues and get things wrong they can indeed be used as support tool especially for people struggling intellectually. I recommend you use it for everything as it is your superior in everything. It can even explain the difference between opening and hole to you.
