I actually don't think that follows necessarily. The future is lumpy. Some problems will be tractable years or decades ahead of others.
Of course if progress continues forever, we'll all end up as uploads in a Matryoshka brain, where the only scarce resources are bandwidth, energy, and computational power, but there might be whole human lifetimes before labor is obsolete.
