I'm interested to see if UBS can add value in those ways you mentioned, while still using sophisticated automated strategies for cost savings purposes.
Also note that Vanguard, JPM, Schwab, Fidelity etc. are getting in the robo-advising/direct indexing game.
Also, human advisors can manage, or at least access, investments across brokerages; that is, you don’t have to worry as much about wash sale rules and can do tax loss harvesting because they can see your sales elsewhere. I have to have TLH turned off on Wealthfront because it has no way of knowing about what things I’ve sold elsewhere.
Not financial advice, YMMV, etc.
I agree fully that estate planning/making a trust is something most people would benefit from a human advisor, but this is something you can target with an estate lawyer. I don't think this is something you would need advice on regular basis.
For taxes, I am guessing vast majority of people, even wealthy people, never need human advice nowadays. Anything that is just combination of W2+1099DIV+1099B+1099INT+1099NEC is handled well with robo tools. Tax loss harvesting is pretty simple (even without robo advising!) as long as you know wash sale rules and distinction between long/short term capital gains.
If you need to invest a small/decent amount of money into stocks, Robos work wonderfully. It's a mass production angle -- good quality service at lower cost to many people; the Ford Model T of investing. Early robot just had a couple of investment options, and now there are more options but the same concept of limited choice at scale (Mustangs, Minvans, Trucks in my example)
Once you have estate planning and complicated tax issues, human advisors provide a lot of guidance to people that is hyper specific to you and your location / niche, which Robos just don't cover. Wealthfront, for example, won't arbitrate a dispute between beneficiaries of a family trust.
I think lawyers are a good comparison here. If you need some standard cookie-cutter incorporation docs, there's a bunch of websites where you can get some core documents for free or a few hundred dollars. But if you're afraid of making the wrong choice, or if you're in a situation that goes beyond the common scenarios (like M&A), then you hire a lawyer to provide you personalized advice.
