we aren't in college to learn a specific skill so much as we are there to learn how to be taught.
I really like this idea, but prefer one small change: I think it's best to learn how to learn.
Learning how to be taught is part of that, and a large part. Understanding when to absorb information, rely on experts, and apply yourself until you improve is fundamental. You won't get any arguments from me there.
But being taught is only one facet of learning. Sometimes experts aren't really experts, or don't have the learner's best interests at heart, or omit things to protect their own interests or ideology.
Learning how to learn involves fostering fundamental curiosity, not being afraid to fail, asking all the questions even dumb ones or those with seemingly obvious answers. Finding out "why" something works instead of just "how". Fundamentally curious people who learn as a habit tend to also develop a scientific method-like approach to evaluating incoming information: "Ok, this is the information I'm presented with, let's assume the opposite, can I prove the null hypothesis?" This acts as a pretty good bullshit detector, or at the very least trains learners to be skeptical, to trust but verify, which is enormously important in the age of misinformation.
Being taught generally tapers off as someone gets older, or becomes an expert. Learning never needs to taper off, so long as your brain still works.
I'm not sure what you're saying. If you write software for Apple mobile devices, you're creating it for iOS. If you write for basically any other smartphone, which represent nearly 75% of all devices worldwide, then you create for Android.
In the US they probably have a huge number of potential customers on iOS, so bringing experts and designing for their iOS experience makes sense, as you point out. But saying that platform is the most popular worldwide would be factually incorrect. You don't write apps for hardware (there might be some small tweaks to take advantage of available hardware like on Pixels), you design for the platform.
Also, it appears that the design for iOS is sound, and OP just fundamentally misunderstands how to share specific sets of photos with Google Photos.
None of this is to defend Google's data collection policies.
