It's a really interesting idea. The only thing I am afraid of, besides the future-proofness of the solution (but what solution is totally future-proof anyway?) which has been already commented at lot here, is what my kids would feel knowing we shared lots of personal stuff using a service from a company that's not exactly known for privacy. Personally if my parents did that I'd be a bit upset because I wouldn't agree in the first point with sharing my personal life (even my past one) with Google (or Meta, for what it matters, although I feel like posting stuff on Facebook is worse), as once it's done, there's no coming back. (EDIT: just seen that xerox13ster actually also commented on the same point, so sorry for the repetition...)
