Yes, as it has been for decades. I also learned some about it back in the early days of the '80s into the '90s. It’s constantly evolving along with the tech (and the capabilities of the current majority of users), so there’s never been much of an absolute set of standards that have withstood the test of time. Again, there are a wide variety of people in the world - all with their own perspectives and ways of doing things. As such, the goal of a universally intuitive interface - while laudable - is a bit of a quixotic pursuit, IMHO. At least until it fully resembles & interacts like real-world objects & beings, anyway.

ETA: They’re more likely eventually going to settle upon a set of standards that is based upon what users have collectively already been forced to learn from using existing interfaces. Once the vast majority of the world’s population is used to and on board with the same way of doing things, that will likely become the “standard” by default. For example, a growing number of people today are only comfortable using their phone, and have never really learned how to use a computer with a similar level of comfort. It will likely remain that way until some new major “paradigm shift” in tech happens (like the shift from PCs to phones) that starts the process anew.
