Hello ! The end of the course is approaching. You have one week left. During this third and last week, we would like to discuss about "the value of digital innovation". Much of the value created by digital products and services is immaterial. Software, online services, platforms… All these assets holding up the digital economy are intangible. This immateriality naturally raises the question of the value of these assets. It is worth noting that the Internet has always been the target of recurring criticism regarding the value created online. The bubble of the 2000s and the fleeting or gimmicky nature of some start-up pitches certainly have not done much for the credibility of digital products’ and services’ value. To fully understand the digital world, you need to be clear about how to assess the value created by digital technology. You also need to be able to tell a bubble from a healthy, sustainable fundamental.
