The problem with that proposal is that we're currently waiting until all of the low hanging fruit got picked. I'm no masochist - if there are nice fruit on the bottom branches, I'm going to pick those. The problem is that the low hanging branches have been picked of all their nice fruit, just leaving the sour, the rotten, and the immature. We could start putting in the effort and climbing the tree for the nice, ripe fruits at the top, but we're being lazy and waiting until we've picked every last worm-filled mush at the bottom.

On this tree called "life", new low-hanging fruit grows every day. It's a reason we see such churn in the sorts of tech that keeps solving the same easy problems in different ways.
