Hardly, asymptotic behavior can be anything, in fact that's the whole question: what happens to AI performance as we tend to infinity? Asymptoting to `y = x` is very different to levelling off.
Deep learning and transformers have given step functions in AI's capabilities. It may not happen, but it's reasonable to expect another step-function development soon.
This argument requires us to believe that AI will just asymptote and not get materially better.
Five years from now, I don't think anyone will make these kinds of acquisitions anymore.
