>> The advantages of having a cross platform application developed in 1/3rd the time especially for new applications are huge (faster time to market, larger number of people for validation) > I'm not entirely sure the premise here is accurate. I suspect that an experienced Qt developer could produce a basic native application in roughly the same time as an Electron developer, but with a fraction of the overhead.

One difference here is there a lot of JS developers available to hire an much fewer Qt or even C++ devs.
