To some people it looks that way, but I am going to say no. The key issue, in my view, is the pursuit of excellence. Can great thinkers, engineers, and entrepreneurs still pursue excellence, or are they being stifled by ankle-biting social justice activists?
I think that the pursuit of excellence is still possible. If the New York Times fails as an outlet, there is still Quillette. If many academic departments become mediocre, excellence will find its way to other departments or the corporate sector or perhaps privately-funded research institutes. If the top tech firms stifle their best talent, venture capitalists will find better uses for them.
I worry about Scott Alexander. His excellence could be harder to pursue if his worst fears about the NYT revealing his name are realized. But on the whole, I think that the ability to pursue excellence is going to still be here.
