Yep I am a transhumanist, didn't realise the terminology so thanks for that, but after a read I agree with the concept in principle.
Bring on the tech, either biotech, or cybertech, wetware or otherwise. For instance I appreciate the concept of a phone with my contacts and various other documents on it, it is a memory device that allows me to 'remember' many more details/contacts than I care to mentally remember. Stuff like that is worthwhile in my opinion and I look forward to more synergy between technology and the human form or capacity.
I agree with a chip in the body in principle for a variety of purposes including location, memory storage, communication, medical data, even identification.
The only issue I have is when or IF such modification or additions to the human form become involuntary or mandated, either by government, family or business. Stuff em it's my body and I will transform it as I wish.
