Anyone following science (or tech, or medicine, or anything) news will (ought to) realize how over-hyped and fluff-heavy every press release is. Real breakthroughs are very few and far between, because progress seems incremental. And because usually those breakthroughs are unseen, uninteresting, not even press-release worthy, because we haven't realized its potential. Then someone tries out that new thing for that old problem, and gets maybe decent numbers, usually just meh. Then slowly it builds, and then eventually comes the paradigm shift. But at that point it's the waiting game, slow march of better and better engineering, getting better trade offs, and so on.
