For this piece of work, I think Jean Jullien implies that now-a-days customers often use the self service till rather than others, which soon could leave people with out a job as customers want to do it themselves and be independent. A lot of people do not realise this because they are only bothered about shopping; they're not there to do anything else. The reason I understand this design is because I currently work in retail where you have self service, but also tills and a lot of people my age use the self service because we don't want to socialise and it's quicker than waiting in a queue. Overall, technology is taking over and people don't see that until it effects them. 

​

To be honest, his work really puts it self out there. It shows what society is like and the illustration is pleasing and creative. I would like to input this sort of work in my development because it's meaningful, but also intriguing to look at.
