A heated debate over the definition of science erupted on X (formerly Twitter), involving prominent figures such as entrepreneur Elon Musk and computer scientist Yann LeCun. The discussion, which began on May 27, centered around whether unpublished research can be considered science.

The Spark of the Debate
Elon Musk, founder of xAI, a company focused on developing AI capable of enhanced reasoning, posted on X, inviting people to join xAI for the "maximally rigorous pursuit of the truth." Yann LeCun, chief AI scientist at Meta and a leading figure in deep learning and neural networks, criticized Musk, highlighting the discrepancy between Musk's claim and his tendency to spread conspiracy theories.

Defining Science: Publication vs. Method
LeCun argued that science requires the publication of research to be considered valid. He emphasized that scientific progress depends on collecting, testing, and sharing knowledge to ensure correctness and reproducibility. According to LeCun, without publication, technological progress would slow significantly.

This assertion drew backlash from various quarters. Critics pointed out that science is not merely a collection of published facts but a systematic method of understanding. Some argued that significant scientific work often remains unpublished, especially in the private sector, where corporate confidentiality is paramount. Estimates suggest that 40% of data from academic and government scientists also goes unpublished.

The Importance of Feedback and Openness
LeCun later clarified that science progresses through the collision of ideas, verification, and improvements, asserting that unpublished research likely has no impact. He and others called for more openness in AI research, specifically the need to publish the source code underlying neural networks. This call for transparency aligns with criticisms that major AI developments, such as those by OpenAI and Google DeepMind, often lack publicly available source code.

Philosophical Perspectives
Philosopher of science Janet Stemwedel and computer scientist Peter Coveney emphasized the importance of feedback and rigorous examination in the scientific process. Stemwedel noted that responsiveness to feedback is a cornerstone of modern science, along with the utility of science for making predictions and providing explanations.

Coveney questioned the scientific validity of methods used in developing generalist AI tools, which rely heavily on large language models like ChatGPT. He argued that machines generating statistical inferences from scientific literature do not achieve true understanding, thus challenging Musk's assertion that explainable AI could replace conventional scientific methods.

The Contention Over Science’s Definition
The debate on X highlighted the contentious nature of defining science. Stemwedel pointed out that Twitter, before Musk's takeover, facilitated beneficial discussions about science, fostering objectivity through collective efforts. In contrast, the current environment under Musk's leadership has become less responsive to reasoned discourse.

Conclusion
The debate underscores the ongoing struggle to define science, balancing the need for rigorous publication with the broader understanding of scientific methods and principles. As technology and AI continue to evolve, maintaining the fundamental ideas of science from the Enlightenment—objective discussion, rigorous examination, and responsiveness to feedback—remains crucial for advancing knowledge and innovation.
