To Eric Elliott’s point: You can do PWA today. You can do PWA tomorrow. But you will eventually end up doing PWA.

It’s really boils down to trends. The native app market is on average, dead in the water. On the other hand, the PWA market looks like blue skies with no limits in sight (or is it site? hehe).

All other things being equal — read: time/cost with an order of magnitude- PWAs make more long term upside sense.
