No particular aspect. Just continuity: something which has evolved from me without any step changes that are “too large”. I mean, assuming that each stage through all of that evolution has maintained the desire to keep living. It’s not my job to put hard “don’t die” constraints on future versions.
As far as I know, something generally continuity-based is the standard answer to this.
You want to be an insignificant, and probably totally illiquid, junior partner in a venture with Elon Musk, and you think you could realize value out of the shares? In a venture whose long-term “upside” depends on it collecting money from ownership of AGI/ASI? In a world potentially made unrecognizable by said AGI/ASI?
All of that seems… unduly optimistic.
