3 Levers for thought
Like the prehistoric farming tools you saw earlier in Figure 3, digital thinking tools have diversified in many ways. Some are very specialised and only do one thing. For example, an app that acts as a clicker and helps keep count of how many times something happens. With each click, it ups the count by one. Other software is more general-purpose. For example, you can use a spreadsheet for many different things: calculating, storing information, graphing, and so on.
A useful way to think of digital tools can be in terms of the key properties that help extend our natural capabilities (Figure 9).
