can we stop looking for 'breakthroughs' - to me that describes a single barrier that when removed all will be plain sailing. that doesn't seem to be the case - there are dozens of achievements, all significant but each only another step on the way Using the word 'breakthrough' is misleading. I am very optimistic, but, as the advert says, it won't happen overnight. so how about cutting 'breakthrough' out and having significant developments? unless of course it really is a breakthrough...
