In many cases, higher salaries tied to 'experience' are essentially paid out because your employee has a higher likelihood of having seen 'it' before than the green salad you hired last month. If life was highly random, this might not work. But established industries work on continuously reducing (if not eliminating) surprises, so the whole basis of certain 'career ladders' is based on the promise of तजुर्बा. In comparison, kids constantly meet new things, until someday, where this plateaus out and the 'surprise' value of events diminishes. Which is perhaps why creative thinking methods try to force surprise on people, through constraints or unexpected situations or trying to map analogies - to push you into unseen mental paths rather than the well-trodden path with enough engine oil on it.
So would a service that injected controlled amounts of surprise into your life be useful to you? Not of The Game proportions, but little things that you had never experienced before or never thought you would see, forcing you to do a double take once in a while? Calibrated, not fully random amounts.
Of course, an alternative argument could be that the older you get the more the intensity of the surprise, because 'I thought I had seen it all, but there you go'.
