Is anyone interested in trying to poke at this idea, and see how many reasonable solutions can be come up with? For example, here's one possible view, derived from certain aspects of present-day law: In several jurisdictions, when Mr. Smith and Mrs. Jones marry, they form a sort of corporate entity, "Mr. & Mrs. Smith", in which some aspects of property and responsibility are jointly shared between them. If there is no specific pre-nup or marriage contract, then local law sets certain default parameters about this corporate-entity, such as how it may be dissolved and the assets split between the members. Local law also sets certain parameters that are specific to such agreements, such as priority of visitation rights. Imagine that, whenever someone makes an alpha fork, or a backup that can potentially become a backup fork, then part of the process includes the creation of a contract between the 'original' and the 'fork' specifically to cover such issues - and if no such contract exists, then local law acts as if a contract with certain parameters is made anyway. Thus, if DPR.0 creates an alpha fork, DPR.1, then either by default or explicitly, a 'contract' is made - most likely involving the creation of a similar corporate entity, in which the property owned by DPR.0 is now owned jointly by both DPR.0 and DPR.1, and setting the parameters by which that joint-ownership system can be dissolved so that DPR.0 and DPR.1 each have separate bank-accounts, property, and full identities. How criminal law treats forks depends on the assumptions behind the law system. For example, let's say DPR commits a crime, and then forks into DPR.0 and DPR.1. If a primary consideration is restoring a victim to their pre-crime status, as best as possible, then it doesn't matter /which/ DPR pays restitution, or if each pays half, as long as full restitution is paid; in this sense, the two DPRs have joint responsibility for the debt. (This would also seem to be the most sensical general approach for many civil contracts in which DPR ends up owing a debt.) However, if the basis for the legal system in question is protection of the citizenry from demonstrably-dangerous criminals, or the prevention of future crimes by inflicting unpleasant punishment on convicted criminals, then it would seem likely that /each/ DPR would be required to endure the sentence in full. Both of these criminal approaches would seem to imply that if DPR.1 commits a crime /after/ forking, then DPR.0 wouldn't necessarily be liable for it, anymore than a wife is responsible should her husband jaywalk. (Ie, depending on the details of the joint-property-ownership of the marriage, the fine may be deducted from their shared property, but she wouldn't be sentenced to jail.) This further suggests that it's in the DPR's best interests to keep as accurate records as possible about which DPRs fork from which other DPRs, and when, so that they /can/ keep track of which DPRs would be liable for what, and, more importantly, which DPRs /aren't/ responsible and liable for debts incurred by other DPRs. Of course, I haven't even /touched/ yet on how to figure out which DPRs would be entitled to vote, among other thorny issues. :) So... what do you think? A key problem with multiple alphas is contract law - and that includes marriage, property ownership and voting in a sense. If I can become two persons, who has the right to my shuttle or husband? Who is responsible for living up to what I promised in that contract? Worse, legal culpability becomes messy: if I commit a crime and fork, are both forks now equally culpable, or is it enough to punish one of them? These are problems law people can solve (and they love coming up with principles for handling things like this), but the solution used in the inner system is to not update the laws surrounding personal identity too profoundly and instead have people keep to one constant identity. Very much a transitional economy thing. Note that having backups is legal, and I think there was a mention that if a really old version of you comes online it is not regarded as an alpha in the eyes of the law (I assume it is now regarded as a possession, which it might not like). Allowing full alpha-forking opens amazing cans of worms. Which means some people are very busy promoting it, of course. An economic singularity is just what the doctor ordered, right? What could possibly go wrong with banyans, copyrations and clades of heavily interlinked forks?
