An autonomous drone carrying water to help extinguish a wildfire in the Sierra Nevada might encounter swirling Santa Ana winds that threaten to push it off course. Rapidly adapting to these unknown disturbances inflight presents an enormous challenge for the drone’s flight control system.

To help such a drone stay on target, MIT researchers developed a new, machine learning-based adaptive control algorithm that could minimize its deviation from its intended trajectory in the face of unpredictable forces like gusty winds.

Unlike standard approaches, the new technique does not require the person programming the autonomous drone to know anything in advance about the structure of these uncertain disturbances. Instead, the control system’s artificial intelligence model learns all it needs to know from a small amount of observational data collected from 15 minutes of flight time.

Importantly, the technique automatically determines which optimization algorithm it should use to adapt to the disturbances, which improves tracking performance. It chooses the algorithm that best suits the geometry of specific disturbances this drone is facing.

The researchers train their control system to do both things simultaneously using a technique called meta-learning, which teaches the system how to adapt to different types of disturbances.

Taken together, these ingredients enable their adaptive control system to achieve 50 percent less trajectory tracking error than baseline methods in simulations and perform better with new wind speeds it didn’t see during training.

In the future, this adaptive control system could help autonomous drones more efficiently deliver heavy parcels despite strong winds or monitor fire-prone areas of a national park.

In December 1993, the New York Times published an article about the “limitless opportunity” of the early internet. It painted a picture of a digital utopia: clicking a mouse to access NASA weather footage, Clinton’s speeches, MTV’s digital music samplers, or the status of a coffee pot at Cambridge University.

It was a simple vision—idealistic, even—and from our vantage point three decades later, almost hopelessly naive.

We can still do all these things, of course, but the “limitless opportunity" of today's internet has devolved into conflict, hate, bots, AI-generated spam and relentless advertising. Face-swap apps allow anyone to create nonconsensual sexual imagery, disinformation propagated online hampered the COVID-19 public health response, and Google’s AI search summaries now recommend we eat glue and rocks.

The promise of the early web—a space for connection, creativity, and community—has been overshadowed by corporate interests, algorithmic manipulation, and the commodification of our attention.

But the heart of the internet—the people who built communities, shared knowledge, and created art—has never disappeared. If we’re to reclaim the web, to rediscover the good internet, we need to celebrate, learn from, and amplify these pockets of joy.

Increasingly, surveillance is being normalized and integrated in our lives. Under the guise of convenience, applications and features are sold to us as being the new better way to do things. While some might be useful, this convenience is a Trojan horse. The cost of it is the continuous degradation of our privacy rights, with all that that entails.

As appalling as it is, the truth is the vast majority of software companies do not consider privacy rights and data minimization practices strongly enough, if at all. Most fail to implement the principles of Privacy by Design that should guide development from the start.

Whether this comes from ignorance, incompetence, greed, or malicious intent can be debated. It matters little, because the result is the same: Technologies collecting (and monetizing) a shameful amount of data from everyone.

This horrifying trend ends up facilitating and normalizing surveillance in our daily lives. It is the opposite direction of where we should be going.

The more we accept this normalized surveillance, the harder it becomes to fight back. It is critical that we firmly and loudly object to this banalized invasion of our privacy.

There are countless examples of this growing issue, but for now let's focus on three of them: Airport face scans, parking apps, and AI assistants.

Ireland is the data centre capital of the world with 89 data centres storing your Instagram reels, TikTok dances and endless folders of photos that keep us connected in the digital world.

Data goliaths like this are at the centre of the rise in AI, with every ChatGPT prompt or AI-generated image requiring huge amounts of data to be processed.

But why should you care?

Because data centres have a major environmental cost too.

In order to keep social media scrolling, data centres use huge numbers of backup and emergency generators to stay online when the electrical grid can’t provide them with enough power.
