How about this: without the time to do them, morally great things cannot be done. Thus any great thing that was done happened in part because the time was made available, and thus making time available is necessary in order for them to happen. If something great and meaningful happens, it was because free time was made for it, and thus some time saving technology enabled it (ie, they didn’t have to spend all their free time foraging for food as in pre-technology days).
I can also show that the inverse is false: it is impossible to do some 'morally great thing' without spending time on it.
I see the advancements happening today on the spectrum of all technology, from farming to medicine to railroads to flight to computing. They all save time, or extend life (create time), and in its own small way (or I would say not so small way) the instant gratification economy is advancing that.
