Re: Sod off.
we're missing a massive opportunity
We're really not. By far the bulk of the work of the NHS is mundane and routine, so any potential improvements are merely around the edges. The biggest opporunity for health improvement is to promote the lifestyle changes that would reduce obesity - that's not even a medical issue. Some of the biggest medical scandals (such as mesh implants) are due to the lax rules for the introduction of medical devices, not the failure to notice their impact.
Facebook promotes the "massive opportunity" that could arise from connecting the world and we've seen where that leads: a trivial reduction in the effort required to communicate with people you don't like at the price of the ultimate destruction of civil society.
