Are you saying that when you make something, literally anything, available for the public to read, then you are ipso facto giving permission for people to copy it and do with it what they will?
also using "enthusiastic consent" to make this argument is super cringe. drawing a connection to someone taking advantage of you because you are asleep is super bizarre.
Imagine an undocumented immigrant who commits a serious crime, like murder. Do you want the local prosecutors to go after them, and send them to jail for a long time? Or do you want ICE to go after them, in which case they ... get deported and wind up living free in another country (putting aside the current debacle with El Salvador and CECOT). Where is the justice in that? If someone commits some sort of crime in the US, I want justice to be served before we talk about deporting them.
Okay, but psychology research like this needs to be taken with context on long term behavior. Is this advice practical? No, not in this case. The problem is that very few people can actively learn that way for multiple hours in one day, let alone be motivated for studying in that intense way for subjects they do not like. Any barrier will stop them. That research applies to cramming for exams, when stressed, which most EdTech isn't really useful for (at that point, people are learning intensely anyway). This human nature has not changed.
And your suggestions (not to be rude) are to excite kids about the subjects they find least motivating. But the problem is already motivation.
Youtube is motivating because it is fun. It might not work, but it fits the motivation level you have.
Why not forget about the strong moats/tendencies of EdTech projects to fail to revolutionise, forget them targetting parents, and either pick a subgroup of learners who actively do want to change how they learn, or work on the motivation problem? Why are some kids so much less motivated to learn Math than others? Should we change that and how can we?##
Here's an example I find interesting: The western world accomplished bringing Biology from dominantly male to an equally balanced subject. How did that change happen? We benefit from all these women researching in Biology. Could it happen to other sciences? Or the reverse? These kind of questions interest me.
The reason some kids are not motivated to do math is because they believe they are bad at it, and nobody likes to do something that makes them feel dumb or not good. The kids that love math (like myself - I remember I was SO excited about math as a kid) are good at it, and teachers are constantly complimenting them.
You can hack the brain to feeling good while learning. I just need like 200M but I might be able to do it without.
As with all things, you need to know your audience. If you are making a product for people over 60, probably a simple username/password would work best.
