Reducing investment in research and innovation slows progress, but directing them towards the wrong problems or the wrong solutions can be even more harmful.

Met chief rejects calls to scrap live facial recognition at Notting Hill carnival Mark Rowley says technology will be β€˜non-discriminatory’ and β€˜does not perform in a way which exhibits bias’

Curious to know more details about how the lack of bias, as claimed in this face recognition system, was assessed and validated!

September 28 vote: Swiss back e-ID but Swiss Abroad remain cautious Electronic ID appeals to a large majority of Swiss, but the diaspora is more sceptical, according to the first poll ahead of the September 28 referendum.

There will be challenges in the introduction of a sovereign e-ID, ranging from its adoption to security implications, and many others! But is it realistic to resist and to ignore the change in economy and society?

How do we trust what we see in an age of AI? This week, as AI experts from around the world gather at the AI for Good Summit in Geneva, Switzerland, the conversation is no longer only about the power of artificial intelligence. It’s about trust.

Consider reading my latest article on the occasion of the AI for Good Summit, taking place from 8 to 11 July 2025 in Geneva, Switzerland, where I discuss JPEG Trust standard!

As Switzerland is the largest foreign investor in R&D in the US, and it has already made significant cuts in its own spending on research, innovation and education, isn't it time to bring some of that R&D investment back home through well thought initiatives?

Swiss Indignant to Make the Top 10 of Trump’s Tariffs List Swiss companies bemoan the loss of a reliable partner, and called the 32 percent tariff β€œincomprehensible.”

Let’s set the record straight on the actual Swiss tariffs on imports from the US, that have resulted in a 31% or 32% tariff imposed on it exports. The tariff on the imports of industrial goods from the US, which represents 95% of its total trade, is 0%!

The key is in the transparency! This is why the JPEG Trust standard second edition is extending its scope to deal with authorship and ownership in addition to authenticity!

Labeling both in visible and invisible ways all AI generated content was something that China had already contemplated in August 2023.
