Microsoft quit growing because of market saturation and legal challenges. The former seems unlikely with regards to technology, and the latter nearly impossible. It is possible for tech to stop growing, yes, but the cause of it would need to be either a massive cultural shift across most of the world, or a civilization-collapsing event. It took a very long time to develop a technological mindset, even with its obvious superiority, so I would expect it to take even longer to eliminate it.
