There's a great interview with Moby which has been nicely summarized here. It's about creativity with digital tools. There's a part when he talks about depth, and how easy it is to sidestep doing the work to get there.
"We’re sacrificing rare creativity that has depth for ubiquitous creativity that is very shallow. Like letters vs emails. A letter was rare, but people would tend to write quite a lot. Emails are ubiquitous and they tend to be twenty words. It’s the same sort of thing with music thirty years ago, someone might work on it for six months, and really struggle and it was rare and perhaps had depth, whereas now, you can make an okay sounding piece of music in 30 minutes but it might not have has much depth. [The danger is] because if you can make something look pretty good with not that much effort it’s hard to push yourself to make something great."
I suppose this has always been true, regardless of digital tools. Just really liked the way he said it.
