Jim, The buttons work correctly in the majority of cases, and automation is progressively improving all the time, but I think there will always be enough cases remaining where pushing buttons produces garbage, so that there will be sufficient demand to keep crystallographers in employment for a while yet. The other evening I was watching a repeat of Star Trek: The Next Generation where Lt. Cmdr. Data (an android for those not familiar with the series) was put in command of a starship, much to the consternation of the human 2nd-in-command who immediately requested a transfer! I don't think we've reached that stage yet!
