We often project our 'superhero' aspirations onto our leaders and vulnerability, and other more human traits, are not always encouraged. Organisational leaders often experience loneliness, and the 'truth' within their company is often illusive to them because subordinates will often tell them what they want to hear.

Look at something like Uber... on balance- it's still a taxi service! In the end, what they designed was a different way to connect customers and a service provider using technology, leading to a better experience for both.

We've entered the age of Peak Water - where the easy sources are already being used and future supplies will be harder to find, more expensive to develop, and come with greater environmental and social costs.
