@dansup just add another thing. The natural barrier is also finances. Bigger insrances need more hardware to operate, that means bigger costs. So at some point instances xannot grow forever on a free as in beer basis and either remain on the max they can afford, or change their buisness model, which then in turn either will make people choose different instance or pay for platform. We have like 7 billion people on the planet. Plenty room for big, small and even huge instances.
