The text discusses how people in tech often overestimate the impact of big things and underestimate the power of small things. It uses the examples of flying cars, chatbots, and VR to illustrate this point, noting that these technologies have not yet lived up to their promises. The author then shares a personal anecdote about designing a chatbot in 2015, which failed to deliver on its hype. However, they argue that perhaps we were looking at chatbots the wrong way, and that small innovations can add up over time. They introduce Custom Bots powered by Operator, a tool that enables anyone to build their own bots, and see it as a small step in a big direction towards a potential chatbot revolution. The text also highlights the importance of understanding that progress is not always linear or binary, and that the future is often built on a collection of small innovations rather than a single big thing.
