Went through JetBrains’ “Tools and Trends – The State of Developer Ecosystem 2025” earlier today and it’s wild how much has shifted in just a year.
Most developers are now focused on building the “connective tissue” between systems – integrating APIs and services instead of just shipping isolated apps, which is exactly the kind of work I’ve been gravitating toward with agents and data workflows. Embedding AI into products has already climbed to the same level as classic data processing and analytics, so “AI inside” is starting to look like a default feature rather than a cool add‑on. One of the charts I’ll attach shows this nicely, with “Integration with AI” quickly catching up to data processing.
On the language side, Python stays near the top, while TypeScript has had one of the most dramatic usage climbs over the last five years, and Rust, Go, and Kotlin keep rising steadily as the new “serious” choices.[4][1] Meanwhile, older staples like PHP, Ruby, and Objective‑C are slowly drifting down, which lines up with what’s showing up in modern stacks. The language trend graphic I’ll include makes this super obvious, with Python holding strong and TypeScript rocketing up.
For my own work, this feels like a good confirmation to double down on:
- Python for AI, data, and automation.
- API‑heavy, integration‑first systems instead of monolithic apps.
- Gradually levelling up TypeScript for frontends and better DX around these agents and services.
