The AI code wars are heating up

Something remarkable happened during the holidays of 2025 when developers with free time began testing Anthropic's new Claude Code tool powered by the Opus 4.5 model. What had been a careful, often unreliable coding assistant suddenly became something that could turn simple sentences into working prototypes. Boris Cherny, the creator of Claude Code, told The Verge he was having AI write 100 percent of his code, saying "It was just as surprising for me as it was for everyone else." This breakthrough sparked what former AI researcher Andrej Karpathy dubbed "vibe coding" — people who couldn't previously write code were suddenly building functional software by simply describing what they wanted. The transformation has sent shockwaves through Silicon Valley, where companies are laying off thousands of developers while citing AI capabilities. Block CEO Jack Dorsey announced 40 percent layoffs, writing that "a significantly smaller team, using the tools we're building, can do more and do it better." As coding becomes democratized through AI, the entire software industry faces what some are calling the "SaaSpocalypse" — a fundamental rethinking of how we value and create software.
