This is similar to the change the music industry is going through. There will always be enough money to fund the creation of good music and good journalism. The question is how it will be distributed in the future, and whether those industries will still generate the profit they used to.
Musicians now release their albums independently for free or cheap, and then make their cash from live shows and selling merchandise. This directly funds the artist, but doesn’t leave room for a record company to take it’s cut. This freaks out the music industry exactly the way the journalism industry is freaking out. I think we are shifting away from following organizations for our news to following individuals and funding them directly. Talking to them on Twitter. Impacting what they cover next. As much as big news organizations try to imitate this, it’s never the same as talking to and donating to an independent journalist. Like the difference between seeing your favorite band in a tight little club and at a stadium. There might not be enough profit around to fund big newsrooms full of reporters at desks, but I am pretty sure there will be enough money for reporters to make a living, especially if they can come together in collectives in coworking spaces like the leanest of start-ups do.
