AI's turbulent history, from the calculator to ChatGPT
The use of the term "artificial intelligence" has indeed never been fully consistent. Experts generally agree on a preliminary definition: AI is a machine capable of carrying out tasks previously thought to require human intelligence. "But what is human intelligence?" asked Anne Laurent, a computer science researcher and director of the Inria branch at the University of Montpellier. "Philosophers, engineers and cognitive scientists do not agree. Its definition changes over time."
If we look at the broad history of AI, it may have been in the 19 th century that the first human intelligence skill fell, conquered by calculating machines capable of multiplying and dividing. But a narrower view often prevails, placing the birth of AI in the 1940s with the emergence of the computer.
1940s: The foundation
One of the very first electronic computers, the Colossus, was used by the British military to break the encrypted communications of the German high command. It was far more powerful than the electromechanical machines that came before it. The machines that followed would be easier to program and capable of running complex and varied algorithms, finally making it possible to experiment with theories about "thinking" machines, which began to circulate at the time. As early as 1943, Walter Pitts and Warren McCulloch imagined the concept of artificial neurons, a simplified model of how human neurons function.

Elon Musk's X fails to deal with Russian disinformation, study says
More than 100 pieces of content published on X from Russian state media and disinformation actors that fail to comply with European rules still appear on the social media platform despite being reported to X, according to a new report. The report commissioned by German non-profit group WeMove Europe, which was shared exclusively with Euronews, found '125 clear sanction-violating posts' on the Elon Musk-owned platform. Some of the posts included programmes from the Russian state broadcaster Russia Today (RT), which has been banned by the European Union since the 2022 invasion of Ukraine. In one instance, the Russian Ministry of Foreign Affairs account on X shared an excerpt from a documentary produced by RT, which shared a false narrative about an Adolf Hitler collaborator who was 'elevated to the rank of national hero by the Kyiv regime'. The post also provided a link to bypass sanctions and access the full film on Telegram. The researchers behind the paper had reported to X all the content deemed illegal under Europe's Digital Services Act (DSA), the bloc's digital transparency rules. The report found that only 57 per cent of the reports of illegal content received acknowledgement receipts, which breaches the DSA. Among the 125 reports, only one post was removed by X. The company said that there was no violation of EU law. In some cases, X responded to the researchers' complaints within two minutes, the report said, suggesting that automation is playing a big role in X's content moderation. The European Commission, the EU's executive body, launched a formal investigation into X this year for breaching the DSA and said it would finalise the investigation before the summer recess, which begins on July 25. However, the Financial Times reported last week that the Commission will miss this deadline as it aims to conclude trade talks with the United States. Euronews Next has contacted the Commission for comment about the latest report and the X investigation but did not receive a reply at the time of publication. In January, French prosecutors also launched an investigation following allegations that X's algorithm was being used for the purposes of foreign interference. The researchers filed the reports to X on July 8 and 9, 2025. While they were met with automatic replies in most cases that X would look into their complaints, in the majority of them, they did not hear back. Euronews Next has also contacted X for comment about the report but did not receive a reply at the time of publication. Russia's online war Under the EU sanctions regime, it is prohibited to offer content hosting services for sanctioned entities, such as broadcasters or sanctioned individuals. Russia has intensified its disinformation campaign in Europe since it invaded Ukraine in 2022, the researchers said. Along with official Russian government accounts spreading fake news, there were also accounts likely operated by the 'Social Design Agency,' a Russian company known to produce Russia's influence campaign 'Operation Doppelgänger,' as well as anonymous users repeatedly posting such material. 'Overall, the volume indeed exploded [since the war]. It's much more significant,' said Charles Terroille, a project and investigative research officer at the fact-checking group Science Feedback who worked on the paper. 'A lot of the posts that we flagged to X are for instance, documentaries, if you can call them that, so 40-minute videos hosted on X that are Russia Today showing, for example, how Ukraine deserved it all or how [President] Zelenskyy and all the government people and officials in Ukraine are just fans of Nazi figures and all these widely false and reported stories that Russia is propping,' he told Euronews Next. Terroille said another Russian method is to fabricate pages that look like well-known Western media outlets and spread them on X. He added that fake news about public health and misinformation about COVID-19 vaccines are still running, among other topics, such as misinformation about the environment and are 'absolutely weaponised' by Russia. For Taïme Smit Pellure, a digital campaigner at WeMove Europe who led the report, the most shocking part of the research was that the content is also translated into people's home languages, such as French, and is 'everywhere' on X. She told Euronews Next that both the Commission and X should be acting faster and that her organisation has reached out to the Commission but it has not had a 'positive response yet'. 'We know they are working on this, we know they are, it's not like they're looking away completely, just taking their time because they want to do it right and we completely understand that,' she said. Another recommendation for the Commission is for European governments to work together in a more coordinated manner to address this issue, said Saman Nazari, lead researcher of civic campaign group Alliance4Europe, who also worked on the paper. 'As long as we stay only working in our own little bubbles, we do not stand a chance against a multi-billion euro influence apparatus,' Nazari said. His recommendation for X is that 'there is not that much nuance. It's straight-up illegal content,' and that 'it doesn't take much time' to find such content and address it. 'This is incredibly low-hanging fruit,' he added.

TikTok employees in Germanys strike over AI taking their jobs
Workers at the social media company ByteDance, TikTok's parent, are on a one-day strike today in Berlin to protest the replacement of staff with artificial intelligence (AI). Trade union group said that around 150 employees will be replaced by Chinese-sourced A models, which ByteDance trained on behalf of the company and external service providers. The job cuts include the phasing out of the entire 'Trust and Safety' department, responsible for content moderation and keeping the platform safe, and the Live department, which says is responsible for contact with content producers. The workers have also tried but failed to get ByteDance to the negotiating table, the union said. 'It is disrespectful of TikTok to shirk all social responsibility and even refuse to negotiate with us,' said Lucas Krentel, deputy regional head of the media division. 'Today, the employees are sending a clear signal that they will not accept this,' he said in a statement. What are workers asking for? TikTok's employees are the first in Germany to strike against a social media company, the union added. It comes after a small group of 50 employees took to the streets last week in Berlin to raise the alarm over the layoffs, local media reported. The employees are holding a boat tour down the Spree River and will hold a rally on land later on Wednesday. The workers on strike are asking for a collective bargain that would include a severance package that 'recognises the difficult, vital nature of their roles,' such as prolonged exposure to highly distressing content. That would include severance payments worth three years' salary along with an extension period of 12 months for each employee. Germany's Dismissal Protection Act says that any employee who is being laid off due to urgent reasons should receive 50 per cent of their monthly earnings for each year that the person worked for the company. The union says the demands are justified because of TikTok's high profits and the replacement of content moderators by AI devalues their specific training and expertise. TikTok's moderators have in-depth knowledge of cultural and political contexts, which they need to identify problematic content. Getting rid of them increases the risk that the platform supports 'manipulative campaigns,' the union said.. The Live department workers who reach out to content creators are 'crucial for reach, monetisation and community engagement,' the union added.. The union also said that many of the affected employees are not German citizens, so losing their jobs could affect their rights to stay in the country. If ByteDance does not come to the bargaining table, says a longer-term strike could come later this month. Euronews Next reached out to ByteDance to confirm the incoming layoffs but did not receive an immediate reply.

AstraZeneca pledges $50bn investment in the US amid 200% tariff fears
AstraZeneca will invest $50 billion (€42.8 bn) in the US by 2030 in a move to expand its R&D and manufacturing there, the firm announced on Monday. This comes as the pharmaceutical giant aims to reach the target of $80 billion (€68.5 bn) in revenue by 2030, with 50% of it hoped to come from the US. The announcement also comes as the Trump administration threatens tariffs of up to 200% on drugs that are produced outside of the US. The new investment announcement is in addition to the $3.5 billion (€3 bn) pledged in November 2024. According to a statement from the company, the US plays a 'critical role' in AstraZeneca's ability 'to launch 20 new medicines by the end of the decade'. What will AstraZeneca produce in the US? As part of the investment, the British-Swedish company plans to build a new multi-billion dollar manufacturing facility in the state of Virginia. This plant will focus on the production of treatments for chronic diseases and is the largest single investment into a facility the company has ever made. '[This] announcement underpins our belief in America's innovation in biopharmaceuticals and our commitment to the millions of patients who need our medicines in America and globally,' Pascal Soriot, Chief Executive Officer at AstraZeneca said in a statement from the company. 'I look forward to partnering with Governor Youngkin and his team to work on our largest single manufacturing investment ever. It reflects the Commonwealth of Virginia's desire to create highly skilled jobs in science and technology, and will strengthen the country's domestic supply chain for medicines.' The site in Virginia will have a particular focus on producing substances which make up AstraZeneca's weight management and metabolic treatment portfolio. As well as the site in Virginia, the investment will help expand facilities and production in Massachusetts, Maryland, California, Indiana and Texas, as well as finding new sites for clinical trials. AstraZeneca already has 19 R&D, manufacturing and commercial sites in the US, and the country is the company's largest market, representing 42% of their revenue. The firm currently employs more than 18,000 people and supports 92,000 jobs across the US. The new investment announcement is expected to create tens of thousands more jobs in the coming years. Howard Lutnick, US Secretary of Commerce, said: 'For decades Americans have been reliant on foreign supply of key pharmaceutical products. President Trump and our nation's new tariff policies are focused on ending this structural weakness. We are proud that AstraZeneca has made the decision to bring substantial pharmaceutical production to our shores. This historic investment is bringing tens of thousands of jobs to the US and will ensure medicine sold in our country is produced right here.'
