Speaking about productivity, software is far from a guarantee of increased productivity - see the case of EHR in hospitals.
Was this conclusively measured? I imagine there are fewer errors or better decisions made due to quick and easy availability of health history.
I trust auditable, easily legible notes over chicken scratch handwriting faxed from office to office in previous years. With EHR, I can also catch healthcare providers writing notes about stuff that did not happen in the visit to cover their ass, although I imagine many doctors do this because a lot of the minutiae is a waste of time that just serves to help in case of lawsuits or billing disputes. But in any case, I would rather have access to that info than not in case in need to dispute it.
The broad economy is different from pure-software companies. Software can eventually only manage information - but many businesses eventually operate on physical things, where people matter much more than software.
