In me this inspires a high-level of cynicism. Now when I hear a startup wanting to "change the world" I'm always curious whose underpaid labor is going to subsidize that change. Underneath all the Silicon Valley virtue signalling about improving the state of mankind you see the same gears and levers of labor exploitation as old-school sweatshop manufacturers like Nike.
And make no mistake, the ultimate goal is to make the "knowledge workers" at these companies just as expendable.
