I look at Vanguard's Target Retirement Date funds as the predecessors to these automated/partially-automated advising services. I'm not convinced the robo-advising can do any better than one of these funds since the fees for the Target Retirement funds are half of Vanguard's advising fee. The vast majority of retirement investors don't need unique advice. They really just need to be saved from themselves. If putting all the decision making in the hands of some software achieves that then I suppose they do provide some value.
