You're a posthumanist too? I assumed from your first post that you were very anti-SI
I understand. I am doing philosophy on the subject. Trying to examine it from all sides. AND, as it happens in this unique case, not only examining the subject from all sides, but BEING it.
Personally, I'm not full speed ahead anymore. Age and experience have made me less rammy. (rammy - full on the throttle or full on the brakes, no finesse) With things of power, -- I worked with 13,800 volt three phase electricity underground -- it is best to step back for a few minutes and at least run a checklist of precautions. I've seen no such checklist in developing a competitor on par with human intelligence or behavior. Here and elsewhere I'm attempting to, among other things, gage attitudes to see what a populace might allow.
What checklist would have prevented the Twin Towers tragedy? We are dealing with at least the same and likely more potential impact on society. On a personal level we'll be dealing with the development of an intellectual competitor. Considering my biologic daughter and son, I'm not especially enthralled by my own abilities in bringing them to adulthood so I advance for caution in bringing the synthetic to full consciousness. Whatever that means.
