After 2 years, my father was finally able to visit us, and meet his granddaughter for the first time! So much love and happiness 🥰 …and also a ton of fantastic cheese freshly imported from France 😜🧀

We need “humane cities” more than “smart cities”. Technology should enable humane goal, not replace them for the sake of “optimization” in the sense of reducing cost or facilitating the life of privileged “happy few”. Increasingly wonder how to apply this mindset to medicine…🤔

I dedicate this citation in @ScienceMagazine of my PhD paper in @PLOSONE 2010, to all the gate keepers, editors & reviewers, who rejected it 9 times and the various committees saying it was a cheap #openaccess journal (in EEG on top :D), so not an interesting result and message!
