- The Bun rewrite in Rust, costing $165,000 for Anthropic API calls over 11 days, is presented as proof of AI's coding capabilities, but the author expresses skepticism about the completeness and costs.
- No release tag has been issued for Bun in 11 weeks post-rewrite, and open PRs from Claude have grown from 1,277 to 2,475 in 18 days, suggesting ongoing work beyond the initial rewrite.
- The true cost of the rewrite is likely higher due to CI/CD expenses and ongoing Anthropic employee involvement, potentially reaching $800,000, questioning its worth and the valuations of AI companies.
- Anthropic's hype cycle around AI is criticized, with the author advocating for cautious evaluation of claims supporting large valuations, noting similar projects like Anthropic's C compiler and Cursor's FastRender have stalled.
- The author seeks a job and calls for a realistic assessment of AI's practical impact and financial sustainability.
