Mark Zuckerberg predicts that by the end of 2025, AI systems will be capable of performing tasks similar to a mid-level software engineer, such as writing, reviewing, and debugging code. This shift will enable smaller, highly skilled teams to develop products more efficiently. Other tech leaders support this view, highlighting that Google already uses AI to generate over 25% of its new code, while startups are adopting "vibe coding" with large language models.
