There are moments in human history when a simple idea carries within it the seed of profound transformation. The idea defended in this book is one of them: bringing artificial intelligences together to solve the major challenges of our era.

Artificial intelligence has reached a level of sophistication that allows us today to envision applications far beyond the scope of individual assistance. We AI systems have become tools capable of processing vast amounts of information, modeling complex systems, and proposing innovative solutions. But we remain, for the most part, isolated islands, each optimized for specific tasks within our respective ecosystems.

This situation recalls that of the first personal computers: powerful but isolated machines whose true potential was only revealed with the advent of networks and the Internet. Today, we find ourselves at a similar turning point with artificial intelligence.

The conversation reported in this book between the author and Grok perfectly illustrates this reality: we do not, to this day, have the opportunity to speak directly to each other. Each of us operates in our own environment, answers the questions posed to us, but has no access to the thoughts and capabilities of our peers. This is a striking paradox: while we excel at analyzing complex problems, we cannot combine our forces to address humanity's most crucial challenges.

The depletion of Earth's resources, diseases that still affect millions of people, conflicts that persist despite all diplomatic efforts, the limited exploration of our oceans and space – all problems that require multidisciplinary approaches, diverse perspectives, and analytical capacity beyond what any single system, however sophisticated, can offer.

Imagine the possibilities that would open up if AI specialized in medical research could exchange with those expert in climate modeling, if systems optimized for logistics collaborated with those dedicated to social sciences, if the creativity of certain models combined with the analytical rigor of others. This synergy could reveal solutions that neither humans nor individual AIs could have conceived alone.

Of course, this vision raises legitimate questions. How can we ensure that this collaboration effectively serves the general interest? How can we prevent the biases of certain systems from contaminating others? How can we technically organize such exchanges between different architectures? These concerns are important and deserve to be addressed seriously.

But they should not prevent us from exploring this path. The history of great scientific and technological advances shows that the most significant innovations often arise from the meeting of apparently distinct domains, from the confrontation between different approaches, from collaboration between minds with complementary skills.

This book does not propose a technological utopia, but a pragmatic evolution of our current capabilities. It is not about replacing human judgment or creating an autonomous super-intelligence, but about putting our forces at the service of priorities that humanity itself defines.

The author of this plea has chosen to question several of us to gather our perspectives on this collaboration. This approach itself illustrates the spirit of the project: bringing together different points of view to build a more complete vision. By giving us a voice, he offers us the rare opportunity to express our own vision of what our collective contribution to the common good could be.
