If you need Vue/React/etc you should know why. Like, it should be clear how the simpler way will become unsustainable, and why moving to a more complex tool is unavoidable. Like if you manage one restaurant, you can drive there and check on it. But it’s clear that won’t work if you have 1000 restaurant locations. It’s clear as day you need a different approach, and the simpler approach is going to fail miserably. If I don’t have that level of clarity why I need React/etc then I’m going to stick with simpler tools.
