In honestly = honestly  I don't trust technology even I am a computer engineer. there is nothing perfect things. = there is no perfect thing. technology is appear from human's working which is dangerous , slow or needs more hands. so technology is taking after human. human is also not perfect logically and physically. when scientist make technology things they make a fault.= when scientists develop a new technology they also make way to destroy it.  it is called the bug. there is = are many bug in complex technology. it is human's limitation, and natural environment is very complex they understand it but don't control of it = the cant control it. for example we can see rocket explosion to outside earth.
main reason i don't trust technology = The main reason why I don't trust technology  is that normally technology's goal is economical benefit. country has a competition to be first developer and want to has ownership of them. so most of technology is appear = technologies develop without perfect validation. so i don't absolutely trust technology , just i use technology for convinient goal. = I just use technology for my convience, and i accept technology has fault anytime. = I know that technology can sometimes go wrong. 
thanks.
