Propose all you want, but offer some evidence. By the way, Newton is still good enough for NASA to guide its space probes (that is when they remember their metric conversions). You are referring to fine tuning of ideas, not obsolescence.
Present day economists are making predictions of economic growth and job growth based on existing models. Those predictions are wrong. The economists publicly acknowledge that their predictions are wrong - and, furthermore, they do not know why.
This suggests a flaw in the existing models.

Newton needs fine tuning. Perhaps that is the case with Ricardo's ideas. On the other hand, perhaps they are, in fact, obsolete.
