> It's great job security for UI experts, but expensive for organizations because they need stack specialists whereby before a one-man-band (or 2) could make useful apps for less than half the cost and time without having to spend years with UI-Yoda to master some screwy layout engine.

My company has a very, very small number of UI experts who are tasked with making sure non-UI folks can build front-ends. It's been a rousing success. We own some documentation and a few tools to make starting projects easy. We teach an hour long workshop that covers everything (React, the npm ecosystem, TypeScript, best practices, etc) and then we let them have at it. It's been a rousing success and nobody has seriously suggested moving back to jQuery or any of the WISYWIG tools.

Sure there is a cost -- you need to hire at least one person with enough knowledge to cut through the bullshit and build the right tech stack. But once you've paid that cost once the payoff is massive.
