This is a wonderful comment. You've put into words what I've felt about the industry these past 10 years. Complexity correlates strongly with onboarding. The more complex your framework, library, or tool, the longer and steeper the learning curve to become productive with it.
This is not about a learning curve, I feel like you will never be productive with any of those javascript framework. Yes, of course there is a learning curve. For react you will be a lot faster after a few month using it. And this curve is a lot longer than for rails(react and rails are just here for example here). But it seems even after being a react god master you will still be x10 times less productive than an av…
This is a very enlightening point, maybe because the creators of React can afford to pay for unproductive gods, and those crazy assumptions are accidentally embedded in their tools, unlike rails, which was built by a guy trying to solve problems in the optimal way.
The real issue is when such tools become the standard for everyone else, and this often happens because giant corporations have the capital to push their bullshit, just to make their hiring process easier.
