Perhaps it's a bathtub curve, but dollars to donuts you'll have an easier time convincing a newbie to not do dangerous shit than someone more experienced. Beyond just doing stupid shit (plunge cuts, circles, arguably dados, whatever) there's professional pressure. Take a look at the whole stone countertop industry (very) slowly coming to terms with silicosis.

Either way I think Sawstop is great. As a hobbyist I wish it were cheaper. Although to be fair a big part of the cost is that Sawstop doesn't sell low end saws — that's nothing to do with the safety tech.
