> By comparison, financial advice is pretty simple, and there is a universally agreed-upon approach that most people should follow to maximize long-term financial health.
What will AI do when those rules, which it's trained on their repetition so much, don't apply anymore? ~8% annual stock gains for the next 40 years may not hold and an 80/20 stock/bond ratio may not be as wise in upcoming decades
Models can be updated when foundations domain knowledge graphs are built on change. As of this comment, target date funds and pensions containing trillions of dollars adhere to the assumptions you mention (asset class allocation, growth rate and return assumptions, safe withdrawal rates ["Trinity study" aka ~4%/year], etc), and so consumers of AI provided guidance assuming these foundations could do much worse (as they already do today due to lack of information, knowledge, will, etc).
You literally just need to stick the Bogleheads forum into your AI assistant of choice for most folks, if they'll listen (which is the hardest part, imho, people want to gamble, not invest, in my experience). Prompt "What is your age?" respond "Optimal target date fund is 20XX fund based on your current age and retirement age, please confirm to set to default for investing." I suppose this will eventually make its way in some form into every banking, fintech, and brokerage mobile app chatbot in some capacity.

If you want to get fancy, crib off of California's now mandatory high school financial literacy curriculum for grounding.

Investing and trading is a dynamic game. If everyone has the edge of certain portfolio to out perform the average, then no one has the edge.
Similarly AI is not going to solve that. Because everyone would end up with similar AI edge until no one has the edge.
People should start with simple universal rules: Stay invested. Buy low cost diversified etf fund. Favor long term investment instead of trading. Learn something from all weather portfolio composition to hedge the risks.
Stock/bond ratios are way too advanced for what's qualifying as good advice here:
> AI consistently advised people to save during their working years, draw down savings in retirement, invest heavily in diversified stock funds, and reduce stock exposure after age 45.
This is analogous to saying to an aspiring software developer, "You should write clean and testable code, have clearly defined API boundaries, and a repeatable build process." All very true, but also so general and basic that it's not helpful.
