The mysterious Mr Fubini

Several years ago, I came across a simple and compelling vision on the adoption and evolution of new technologies, known as Fubini’s law*:

1. People initially use technology to do what they do now – but faster.

2. Then they gradually begin to use technology to do new things.

3. The new things change life-styles and work-styles.

4. The new life-styles and work-styles change society …

… and eventually change technology.

Since the lines above apply to many technology domains I worked on throughout my career, I have cited Fubini’s law many times in my presentations. Just think of how technologies like broadband internet, digital TV, and mobile communications have changed the way people live, work, and play.

In analogy with Moore’s and Metcalfe’s laws, about which I wrote in an older post on this blog, I have always assumed that Fubini’s law was invented by a person carrying the name Fubini. But, in fact, nobody seems to know who Mr (or Mrs?) Fubini actually is (or was), for which purpose he (or she) formulated this law, or when and where it was originally published. I ran a Google search to find out more, but this only yielded a handful of blog posts (the oldest ones date from around the year 2003) and books that refer to each other.

I have always been convinced that Fubini’s observations are spot on. And even if it’s not my style to quote anonymous or unverified sources, I will keep on using his wise words in my presentations. To illustrate the transformative power of technology and to celebrate human inventivity!

(*) note: Fubinis law, as described above, shouldn’t be confused with Guido Fubini’s theorem that dates from 1907 and describes how to compute a double integral using iterated integrals.

Smile and the world will smile with you

The success of a presentation often depends upon your interaction with the people in the room. To create a true dialog between a speaker and his/her audience, it’s important that they both feel comfortable with each other’s presence. Presenters who aren’t capable of building this rapport may fail to communicate their message, lose their audience’s trust, or deter the latter from asking questions or engaging.

As such, body language and non-verbal communication are powerful tools for putting people at ease while helping yourself to relax. Use positive gestures… Make eye contact… Smile…

A few weeks ago, I delivered a keynote presentation at Connected Cars Europe. One of the sessions at the event touched upon the relationship between self-driving cars and pedestrians. Of course the speaker covered the obligatory ethical minefield of the driverless car forced to decide whether it would kill a group of elderly people rather than a woman with a stroller.

The presenter also gave an interesting answer to the question on how autonomous vehicles may interact with humans to enhance their safety perception. Pedestrians crossing the road often engage with motorists – driving towards or waiting at the intersection – by making eye contact to make sure that the driver noticed them. But how would they feel when this driver is reading a newspaper (while the car is doing all the work on his behalf) or even when there is no person at all sitting behind the steering wheel?

Research has revealed that almost than 60% of pedestrians don’t trust self-driving cars. That’s why a Swedish company introduced a concept car with a front radiator grille display that… smiles at pedestrians. Watch the video below.

This smiling car is just one possible way for future self-driving vehicles to communicate with people around them and avoid confusion or accidents. And just like the public speaker and his audience, both the car driver (or driverless passenger) and the pedestrian will enjoy the experience, and feel more at ease when crossing the street.
