R&D doesn’t happen by just theorizing what the maximum the market could sustain and then conjuring up those innovations out of thin air. It happens via sustained investment decisions over years. Those decisions are made in light of their costs and incentives, which change over time. Either food can be “improved” under certain economic conditions (which are probably amplified by GLP-1s), or we’re at the theoretical maximum. So you can give an argument why GLP-1s don’t produce strong incentive for R&D or you can argue that a stronger incentive won’t matter because we’re capped out, but historically the “if it could be better it would be better already” argument is disproved by capitalism on a daily basis.
