Tech Industry at a Glance (2024 → early 2025)
Quick Snapshot
Developer boom: GitHub’s community surpassed 100 million developers, who made 5.2 billion contributions across 518 million projects in 2024. github.blog
AI goes mainstream: 76 % of developers are already using or planning to use AI tools; ChatGPT is the most-used assistant (74 % want to keep using it) and 41 % of those users also plan to use GitHub Copilot. survey.stackoverflow.co
Language shake-up: Python overtook JavaScript as the most-active language on GitHub, while JavaScript still tops day-to-day work on Stack Overflow; Rust remains the most-loved language (83 %). (github.blog & survey.stackoverflow.co)
Asia rising: All eight metro areas with ≥ 500 k tech workers are in Asia (Bengaluru, Beijing, Shanghai, Tokyo, Delhi-Gurugram, Hyderabad, Mumbai, Shenzhen). visualcapitalist.com
Polyglot stacks: Market leaders mix multiple languages, micro-services, and hybrid cloud to scale—no single “silver-bullet” stack. (maddevs.iomaddevs & itexus.com)
1. Most-Used Programming Languages (2024)
| Rank | Stack Overflow (% of devs) | GitHub Octoverse |

2. What Do the Giants Run On?
| Company | Core Languages | Notable Frameworks / Tools | Data & Cloud Backbone |
|---|---|---|---|
| Netflix | Python, Node.js, Java, Kotlin, Swift | React UI libs; Dynomite cache clustering | Cassandra, MySQL, PostgreSQL on AWS (EC2, S3, RDS) maddevs.io |
| Uber | Python, Java, Go, Node.js, Swift/Kotlin | 100 + micro-services; React; Kafka; Docker/Mesos | MySQL, PostgreSQL, Cassandra; Hybrid multi-cloud + on-prem maddevs.io |
| Spotify | Python, Java | Hub framework; Docker; Apache Storm | BigTable, Postgres, Cassandra on Google Cloud maddevs.io |
| TikTok (ByteDance) | C/C++, Java, Python, Go, Swift/Kotlin | React (web); Kubernetes; Spark & Flink streaming | Cassandra, Redis; Hybrid GCP + AWS infrastructure itexus.com |
| Airbnb | Ruby on Rails, JavaScript/React, Java | RoR micro-services; Webpack; Jest | MySQL, Redis, Hadoop on AWS maddevs.io |
Pattern → every consumer giant is polyglot & cloud-native, blending rapid-build languages (Python, Ruby, Node) with high-throughput ones (Java, Go, C++), stitched together via micro-services and global cloud infra.
3. Fast-Growing Tech-Talent Hubs
| City | Country | Tech Workers (2023) |
|---|---|---|
| Bengaluru | India | 1 M + |
