Google's new code is now 75% AI-generated — a major shift in how software gets built

Google CEO Sundar Pichai announced that three-quarters of the company's new code is now written by AI tools, not human engineers. Meta is pursuing the same target and expects to reach it by midyear — signaling this is becoming standard practice across big tech.

AI code generation works by analyzing existing code patterns and automatically writing new functions, tests, and boilerplate — the repetitive parts engineers usually spend hours on. This doesn't mean humans are writing nothing; instead, engineers now spend time reviewing and refining AI drafts rather than typing from scratch.

For software developers and engineering teams, this means your daily workflow is shifting: you'll spend less time on routine coding tasks but more time validating AI suggestions and handling edge cases the AI misses. Teams that adopt these tools gain speed; those that don't will find their competitors shipping features faster.
