Yes I think that is very true about advisory. In the retail space a lot of the value prop for an advisor seems similar to a personal trainer -- someone to keep you accountable. At the "more money, more problems" level, advisors actually do become busy executing specific tasks -- monitoring and trading multiple accounts, negotiation among family members, real estate agents, or PE firms... -- tech is empowering advisors to do more rather than replacing them.
I like Arta's pitch as a "digital family office" that handles more than just investments. Managing investments is still table stakes, but they also throw in estate planning and other offerings that a traditional financial advisor would offer.
I tried Titan a while back and found that less compelling as a "hedge fund / active management roboadvisor". It didn't seem to differentiate sufficiently from the passive roboadvisors or what traditional wealth management could offer.
