Introduction

In January 2021, a TikTok user with Parkinson's posted a video expressing anger over how tiny are the pills for treating Parkinson's. Brian Aldridge saw the post and used his software to design a pill bottle that solved the problem. In less than two weeks from the original post, someone had created a working prototype of this pill bottle. This is an example of markets at work. People come together, they voluntarily do things in their mutual benefit.
