Terence Tao on AI as a monopoly held by one or two companies

Submission URL | 35 points | by belter | 3 comments

In a recent discussion highlighted by Manuel Ansede, renowned mathematician Terence Tao, often dubbed the "greatest living mathematician," shares his perspectives on both complex mathematical challenges and the integrity of elections in Venezuela. Tao, who has made substantial contributions to mathematics including tackling the notoriously difficult Navier-Stokes equations, applies his analytical prowess to recent electoral outcomes that raise eyebrows due to their anomalously round percentages.

Tao argues that the precise nature of the reported results—down to the last decimal—makes the idea of fair elections nearly implausible, suggesting instead a high probability of manipulation. He relies on Bayesian probability to emphasize how unlikely such results would be under normal conditions, proposing that both incompetence and corruption could explain the discrepancies, but leaning towards the latter given the lack of detailed constituency data post-election.

Engaging and insightful, Tao also touches on broader themes such as the potential risks of generative AI, which he is currently advising the U.S. government on. His multifaceted expertise not only reaffirms his status in the mathematical realm but also showcases the relevance of mathematical reasoning in real-world issues, linking abstract problems to societal implications.

In the discussion following Terence Tao's insights, several commenters expressed their thoughts on both the implications of his views on Venezuelan elections and the broader context of artificial intelligence (AI).

  1. Shtr remarked on Tao's healthy viewpoint regarding AI and questioned if it could lead to shorter-term refreshing changes in mathematical discussions.

  2. Blckybltzr emphasized the dangers of monopolistic control in AI, suggesting that larger companies hold too much power over GPU regulations and AI development, which may hinder smaller entities from contributing. They noted the importance of transparency in AI training data and the risks posed by censorship, arguing for more open-source models to mitigate manipulation risks.

  3. Kll contributed to the discussion by highlighting the technical specifics related to open-source AI, mentioning the need for randomness in model training and referencing the immense computational effort required to replicate complex models.

Overall, the discussion reflected a blend of admiration for Tao's mathematical insights and concern over the ethical and practical challenges posed by AI and monopolistic practices in the tech industry.
