I definatley think we need both, and
Religion and science could work well if they worked together and not be so blind sited by their views, which are as old as some of the Drs and Priests/Monks/brothers etc that are still there (I think Methuselah may be on his way out now though

),
religion is so strict in the doctrines that they made up (and yes they did make them up, as they are no longer in their original forms and have been edited to suit their needs of control) that they are just as bad as the scientist, so I agree with you!!
Technological Advancement is not necessarily done by
scientists, the everyday joe has been know on many many an occassion to make huge advancements where science could make none, where the everday person has taken the time to study something and thinks not in the same lines as the above do, so they are open to new ideas and can add and even better the current knowledge because they dont exclude.
Either or we are damned if we do and we are if we dont, when it comes to
scientists/ and religious figures. We place to much trust in people that a lot of the time rely on old knowledge.
