*reads up* Ah. Let me clarify something.
Dr. Halberstam's research which, as I recall, eventually wound up being chiefly sponsored by MCT, began with his 'Matrix Born' research before 2050. After the failure of that project for UCAS Data Systems (which failure was instigated by Lucifer and planned / carried out by Rennie, as per the fiction in the original 1e Matrix book), Halberstam decided that the issue was that the children in the experiment still had bodies - and hence started in on 'unincorporated' children in or around 2052, if not earlier. The information about him (both IC and OOC) in the first Threats book states that he has problems getting the brains to live past six months.
Fifteen years later, 2065 rolls around, and MCT has apparently managed to develop in the longevity department far enough that the corporation is willing to a) do this full-brain extraction to adults, and b) implant them in 'drones' (i.e. full cybernetic/vehicular bodies). The statement at the time of this revelation - which was 2070, not 2065 - is that the adult minds experience, and continue to experience, severe psychological issues. Sure, the brain under discussion (Jon Miller / Gavin Fontain) appears to have lasted five full years - but he's having severe psychologial problems.
In the 5 years since that posting, the psychological issues are unlikely to have been solved. In the twenty-five years since these experiments started, the pure longevity factors have apparently been more-or-less solved (if you call a 5-10 year lifespan, down from at least 40 successfully solved) but the baseline physical issues (uncontrolled metastasis, TLE-x, etc.) would remain unsolved - and potentially unsolveable, as they remain the constant issues a cyborg or cyberzombie IMO should have to deal with, or at least worry about.
I do, in essence, stand by my statement of 'five years', however. 2070 is when we found out about it, and they hadn't solved the issues - which isn't surprising, since they've been struggling with those issues for twenty years. 'Ten years later' is, at least in my mind, not 2075, but 2080. And I expect them to still be struggling with all the same issues.
