If it works, it works. Not sure what level of math and physics we are talking about here, but university mathematics usually doesnt have "problems" in the common sense. Sure, there are going to be questions on the exam which you can solve using the theory or by remembering similar questions. But, upcoming topics are going to heavily rely on the theory, not on the applied methods for problem-solving. So you might start having problems there. But again, if your system still works for that, who cares.
Also, if you are aiming to become a Doctor / Professor / stay at university, youre going to need to remember the theory. Pretty sure there wont be a way around it.
I dont think its about availability, more about the convenience of having everything in one place and especially the rating system (which of course only works if you have a huge customer base and is also being exploited so not really a plus for Amazon anymore)
Level scaling is usually used to make development easier, so making it optional would require the extra work to come up with appropriate enemy strength and the eoptional scaling effect on top.
I have a monthly recurring donation to the GiveWell Top Charities fund. GiveWell ranks charities by efficiency (i.e. impact per dollar) and distributes the funds donations to the most effective ones. Those include fighting malaria, world hunger, child blindness,...
What you are probably imagining when talking about 0 and 1 are their representatives in the "integer ring" or maybe the ring of real numbers. Both are simply definitions made by humans and in no way universal truths.
Oh no, they bought a camper and a pool, those dirty criminals. We should give 100x more of our money to those who really deserve it, so they can buy their third private jet.
Not my experience but nice meme^^
