Why is technology so stupid

You know, for all the advances in technology there are still problems. Take for instance these damned webcams. I just bought one and it says it is ready to go for conversing over the net. I set it up and get online with my sister only to have her not be able to hear me, even though a mic is on the camera. Then I reinstall the camera and it totally fails. I get so sick and tired of technology being so stupid. It is more headache then needed, or am I just too quick to give up on the technology?
