Black hole mergers modelled in 3D

-
Simulations on a supercomputer have allowed Nasa scientists to understand finally the pattern of gravitational waves produced by merging black holes. The work should help the worldwide effort that is currently underway to make the first detection of these "ripples" in the fabric of space-time.

Mind the app - considerations on the ethical risks of COVID-19 apps

-
[22 April update: at the Digital Ethics Lab (OII, University of Oxford) we have elaborated a list of 16 questions to check whether an app is ethically justifiable, the full article, open access, is available here ] There is a lot of talk about apps to deal with the pandemic . Some of the best solutions use the Bluetooth connection of mobile phones to determine the contact between people and therefore the probability of contagion. In theory, it may seem simple. In practice, there are several ethical problems, not only legal and  technical ones . To understand them, it is useful to distinguish between the validation and the verification of a system.  The validation of a system answers the question: "are we building the right system?". The answer is no if the app is illegal,  for example, the use of an app in the EU must comply with the GDPR; mind that this is necessary but not sufficient to make the app also ethically acceptable, see below; is unnecessar...

On the importance of being pedantic (series: notes to myself)

-
Image
They say that to call someone pedantic is an insult. I'm not so sure. True, someone pedantic is obsessed with minor details, small errors, or tiny imperfections. And a pedantic is also someone who cares too much about all such things not to let you know about them, advising or correcting, disagreeing or disapproving. And yes, if you are a pedant, you are more than just occasionally pedantic. This can happen to anybody, the excessive emphasis on some narrow or boring detail being a tendency we all share when it comes to matters about which we care very much. But if you are a pedant, being pedantic is your daily stance, your intrinsic nature, your way of living. You are always, consistently, reliably, systematically pedantic, from the moment you wake up, about the exact place where the slippers should be next to your bed, all the way to the moment you go to sleep, and the exact place where the phone should be placed to recharge. If you are a true pedant, no detail is too trivial, no ...

(revised on Medium) On Kia and Pelé (series: notes to myself)

Image
They say there are only six connections between any two people on this planet. Maybe. My mum once danced with Juan Carlos I (her mother taught piano at the Spanish Embassy in Rome). My sister-in-law knew the Queen. And my brother met Pope Benedict XVI. I should be indirectly connected to a lot of people. But the most amazing link is another. And this is the story I wish to tell you. 21 June 1970, Mexico, World Cup final. A memorable game, even for a child born in Rome in 1964. Italy lost against what is still considered the greatest Brazilian football team of all time . But this is still history, not my story yet, which begins a year earlier.   In 1969, the Brazilian team was training in Rio de Janeiro. They had their headquarters in São Conrado. At the time, the place was far from downtown. The atmosphere was relaxed and friendly, with people meeting the players, and the occasional BBQ.  One girl, six years old, was often seen mixing with the team. She liked football. Her par...

Between a rock and a hard place: Elon Musk's open letter and the Italian ban of Chat-GPT

-
Image
Interview by Adele Sarno for HuffPost, the Italian original is here The following English translation is provided by Google, apologies for any imprecision. Luciano Floridi, the digital philosopher, works between Oxford and Bologna, from next summer, he will leave Oxford to direct the Center for Digital Ethics at Yale. He has received the highest honour granted by the Italian Republic: Cavaliere di Gran Croce. According to the Elsevier Scopus database, he is the most cited living philosopher in the world. If today we talk about the "philosophy of information", it is thanks to him, who for 30 years, studied the connections between philosophy and the digital world. Professor Floridi, ChatGPT has been at the centre of the debate, especially these days. Elon Musk and a thousand other experts have written a letter asking for its development to be stopped for six months. In Italy, on the other hand, the privacy guarantor has decided to stop for 20 days until it complies with the pr...

On the value of taking care of the roses (series: notes to myself)

-
Image
They say that what matters sometimes is not the outcome but the process: not the success or failure of an action, but just the action itself.  Maybe. But I always thought it was a bit of sour grapes. Didn’t really want beautiful roses in my garden, kind of line of thinking. The important thing was gardening. Or so you tell yourself, trying to be convincing.  But I recite this loudly a few times and it still sounds quite lame. It's the philosopher's fault, because he asks the unpleasant questions. Would you have done it anyway, even if the roses had no chance? But above all, what if the process itself is also pointless? Perhaps the gardening is a failure too, like the dead roses.  So you pause, on your way to the roses, and think: if the outcome is not what matters, and the process is not what matters, why caring for the roses? Better stop, or kill the realist awareness that shows the worthless nature of the whole enterprise.  Is there anything left, if all is ...

The Loebner Prize from a judge's perspective

-
Image
This year, for the first time in its history, the Loebner Prize competition was held in England, at the University of Reading to be precise. It was organised by Kevin Warwick and Huma Shah. Independently of whether Turing might have been pleased (he was not well treated in this country, recall?), there was a satisfying sense of “coming home” of the Turing Test (henceforth TT ). Expectations were high, and they very highly advertised too. The meeting was perfectly organised. Having been invited to play the role of a judge, together with several other colleagues, including two members of the IEG , Mariarosaria Taddeo and Matteo Turilli ( here are their pictures and Rosaria's interview ) , I enjoyed the opportunity to see from close-up the machinery and the TT . It was intriguing and great fun. Because there were interviews with the BBC and other things going on, and because we were also supposed to take part in the parallel AISB Symposium on the TT , I had time to test only...

The fight for digital sovereignty: what it is, and why it matters, especially for the EU

-
This article is forthcoming in Philosophy & Technology 33.3 (September) 2020,  as Editor Letter. Digital sovereignty seems to be something very important, given the popularity of the topic these days. True. But it also sounds like a technical issue, which concerns only specialists. False. Digital sovereignty, and the fight for it, touch everyone, even those who do not have a mobile phone or have never used an online service. To understand why, let me start with four episodes. I shall add a fifth shortly. 18 June 2020: the British government, after having failed to develop a centralised, coronavirus app not based on the API provided by Google-Apple,  gave up, ditched the whole project (Burgess 19 June 2020), and accepted to start developing a new app in the future that would be fully compatible with the decentralised solution supported by the two American companies. This U-turn was not the first: Italy (Longo 22 April 2020) and Germany (Busvine and Rinke 26 April 2020, Lom...
