Developers using OpenAI's API are warned that Sam Altman will analyze their usage data to identify and build competing features. This follows the classic playbook of platform owners like Microsoft and Facebook who studied third-party developers to absorb the most valuable use cases.

Contamination in coding benchmarks is subtle. Instead of just spitting out a known solution, models like GPT-5.2 use implicit knowledge from their training data (e.g., popular codebases) to reason about unstated requirements. This makes it hard to distinguish true capability from memorization, as the model's 'chain of thought' appears logical while relying on leaked information.

Stack Overflow, a valuable developer community, declined after its knowledge was ingested by ChatGPT. This disincentivized human interaction, killing the community and stopping the creation of new knowledge for AI to train on—a self-defeating cycle for both humans and AI.

The original Semantic Web required creators to manually add structured metadata. Now, AI models extract that meaning from unstructured content, creating a machine-readable web through brute-force interpretation rather than voluntary participation.

With public data exhausted, AI companies are seeking proprietary datasets. After being rejected by established firms wary of sharing their 'crown jewels,' these labs are now acquiring the codebases of failed startups for tens of thousands of dollars as a novel source of high-quality training data.

Top-tier coding models from Google, OpenAI, and Anthropic are functionally equivalent and similarly priced. This commoditization means the real competition is not on model performance, but on building a sticky product ecosystem (like Claude Code) that creates user lock-in through a familiar workflow and environment.

The proliferation of low-quality, AI-generated content is a structural issue that cannot be solved with better filtering. The ability to generate massive volumes of content with bots will always overwhelm any curation effort, leading to a permanently polluted information ecosystem.

When all major AI models are trained on the same internet data, they develop similar internal representations ("latent spaces"). This creates a monoculture where a single exploit or "memetic virus" could compromise all AIs simultaneously, arguing for the necessity of diverse datasets and training methods.

As AI rapidly generates code, the challenge shifts from writing code to comprehending and maintaining it. New tools like Google's Code Wiki are emerging to address this "understanding gap," providing continuously updated documentation to keep pace with AI-generated software and prevent unmanageable complexity.
