Well, personally, I could very well do without (i) attachment & (ii) feelings. In my book, Ts are humans and as fallible human beings, i.e. as any human being, attaching et al. only leads to heartache. So yes, it would suit me quite fine to be like a(n) (unfeeling) robot.

PS: I am only talking for/about myself. If attaching et al. works for others, fair enough and I am most certainly not judging.
