What is vibe coding and why does it get so much hate?

Vibe coding, coined by Andrej Karpathy in February 2025, refers to using large language models such as Cursor Composer with Sonnet to generate entire codebases, a practice that has expanded as LLMs improve. Research from Georgia Tech identified 74 vulnerabilities—14 critical—among 43,000 advisories linked to AI-generated code, and a survey of 1,100 programmers found 72% use AI tools daily, with 42% of their code AI-generated or assisted, projecting over half by next year.
