It might be worth looking at it from the coffee's point point of view. They'd like to taste their best when you drink them.
The bulk of the world's coffees aren't very good, and can only play in very big marching band blends where all the other coffees cover for their weaknesses. These are the commercial coffees that go into the supermarket cans.
The conventional wisdom is that espresso machines, with their amplified taste systems, are best for small combos, jazz trios or rock bands, of good but not great coffees, while the super star soloists only play "unplugged" in regular brews. The idea of SO espresso is to challenge this assumption, and invite some of the great coffees to plug in, and do their stuff at 100 decibels.
This is a wonderful concept. But it fails miserably if the result is worse than a brewed coffee; then you've just used thousands of dollars of equipment to turn a great coffee into a screech of feedback. Many people, after a few experiences like this, generally eschew SOs as a waste of good coffee, except for the rare Jimi Hendrix beans. Others keep trying and getting the feedback.
My personal take is that this is still an area for the engineers -- we still need to learn how to reliably set up espresso equipment so the best coffees can shine on it. I'm working on it, so are a lot of others; and I don't think it will be too long before it's accomplished. Once it can be done, cafes and home baristas will need to change their grinding set ups to accommodate multiple coffees, and then SOs will become the rule. But for now, it's mostly a way to destroy good coffees.
