I believe the key thing you are missing here is that there is probably an expectation that AI based coding tools will be more mass market, rather than traditional developer market. ie it's a mistake to estimate the potential upside by looking at the size of the current developer market. As you move you're coding tools towards a less technical customer base - there are two synergistic effects - your potential customer base is much much larger, and they are simultaneously less technically competent on average ( and so less likely to build their own tools if you charge too much ). Whether those assumptions are true - time will tell - but I definitely see more people thinking software development is now accessible to them.
