Ordinary people using devices created by very clever folks, find them hard to use. Not surprising.<p>Maybe that does mean they suck. More accurately, they are mismatched with the skill level of some customers. Which is a flaw, surely, you want to make money, you gotta place the device somewhere on the bottom half of the bell curve, maximize the customer base. Go too far, you start losing the top tail. Complicated.
Many highly intelligent people are bad with the so called “technology”. I wager that non negligible number of mathematicians among others fall into this category.
They do not seem to bother.
