For example, one 'technological product' I cannot abide by, and for which I routinely consider reaching our for a sledgehammer, is the automated supermarket check-out. Its intelligence and UX is abysmal. It's slow, unresponsive, pedantic, intolerant, and cannot rely on itself without continual help from a bored mind-numbed shop assistant.
What is missing is a technology that is fast, responsive, tolerant, intelligent and autonomous. You might ask well how would that be possible. That's the point. We or the people that build it, don't have the know-how or wherewithal to do so.
It is clear the technology we do have is not the best that we can possibly develop; and for many reasons, there is not an interest or desire to do so.
