The rate of technological progress will naturally slow to a near halt within the next 100 years

I think that, with very little real action being taken against global warming, and oil not being a renewable resource, an assumption like this could be reasonable.

With the advent of brighter minds, increased education, focus on technological breakthroughs, and adaptive technology, the increase in technological discoveries will only increase.

Of course it will. The focus will shift from activities such as curing illnesses to convincing people that they aren't really sick.
