Reality Check
You can map every thought you’ve ever had — just don’t forget to actually think them first. These tools are only as smart as the connections you make, and most people can’t even connect their phone to WiFi without calling tech support.
The internet gave us unlimited knowledge and we used it to argue about pineapple on pizza. At least now you can visualize the argument.
