Innovation in specific areas slows or stops all the time. The general run of technical progress in a specific area shows an S-curve, in which initial discoveries are made slowly, later progress accelerates as synergies are exploited and greater investment is made, and finally innovation decreases as low-hanging fruit is exhausted and the shape of available technology matches that of the problem domain. For an example of this, see aerospace; it took around sixty years to go from the field's inception to the moon landing and the Concorde, and in the fifty years since we've made mostly incremental progress over the technologies involved in both. It seems that we're currently approaching the top of the S-curve for computation via integrated circuits; further increases going forward are likely to be incremental and margin-focused, as opposed to paradigm-shattering. Maintaining the 1950-2010 rate of productivity improvement will require new paradigm-shattering advances in some other field (machine learning? Internet of Things stuff?). It's possible that these are indeed forthcoming, and we can continue our absurd growth levels for another fifty years. It's also possible that we're nearing the edge of the problem space and we won't have any more easy order-of-magnitude productivity boosts. If the latter is true, then our economy will inevitably collapse with enormous collateral damage. As an economic system, this seems unstable at best.

This doesn't seem like a reasonable worry really. We will continue to innovate at a more rapid pace until we have real AI or there is a massive disaster(runaway global warming of 8-10 degrees or nuclear war are the most probable), I personally think it will be AI though because I suspect we might be looking at 20-30 years until that happens. Once real AI comes I'm not really sure what will happen because it is unpredictable how the AI will be made, but if the past is any indication it will be made recklessly in a race between a bunch of companies. Idk how long our current world order will continue to exist and how much the AI works with us after that event. Hopefully the zoo it keeps us in will be nicer than the way we have treated animals, and hopefully that takes 20 years after the birth of real AI. I wouldn't worry about innovation slowing down, I would worry about the end of meaningful human innovation that we are clearly headed towards.

"Innovation in a specific area slows or stops all the time" Yes, but the general pace of innovation in the entire economy including areas that are slowing down or starting up is pretty consistent. One thing I'd like to make clear is I'm not just talking about 1950-2010 growth rate, I'm talking Industrial Revolution (around 1800 depending on where you are) to now. Ever since society realized we could build machines fueled by energy to increase productivity we've been growing at roughly a 2% pace. Even if it isn't immediately clear where the new productivity gains will come from (although I'd argue there are plenty of promising areas) I think it's more likely than not going to continue. some possible areas - AI, 3d printing, falling renewable energy prices, continued marginal gains from computers, quantum network communication, longer term - quantum computers, expansion of VR, driverless cars, etc. Point being there are a lot of promising areas on the horizon.
