Technology is just a tool like a hammer, though; a means to an end but not the end.  This makes the word technologist, transhumanist, and all derivatives like that kind of like saying you're a stapler.  It's not hard to make the argument humans have no purpose (nihilism), but if you think the opposite, there's definitely not going to be any purpose found in being a stapler.  

That's my theory for the Fermi paradox, that human direction is entirely based around primitive things like reproduction and if you genetically engineer that out or somehow evolve past that, you likely lose the will to live at the same time and then just disappear.  The less depressing version of events would be that once achieving that stage you have reached some type of level of transcendence and no longer need to be around here.
