Would you spend 599 bucks to save your brain? What about 20? Honestly - I think having a dumb phone could be a good thing. Am I strong enough to do it myself? absolutely not. But I think limiting the sludge of social media flowing into my brain is absolutely something I need to be better at. You can do what you want obviously - but adding the greyscale filter to your Android or iPhone (found in the settings) is an interesting first step!
