Not surprised about Python, since it became the go-to language for 'everything AI' related even before the huge boom. If you ask to write a simple script in Claude Code, it will, in my experience, write it in Python. OpenAI buying Astral and Anthropic buying Bun shows that the top 2 lines will grow even more, in my opinion. Public repositories are skewed highly by vibe coding and automatic code generation, again in my opinion, so it also depends on what the clients think about their 'default' language to generate code.
