Artificial intelligence is transforming software development by enabling even non-programmers to create applications through “vibe coding.” AI can automate coding, testing, and business workflows, making software creation faster and more accessible. However, when software is built for clients, reliability, security, maintenance, and accountability become critical. In such cases, software engineers remain essential for understanding systems, validating AI-generated code, fixing issues, and ensuring long-term stability. AI also introduces economic and technical challenges, including token costs, infrastructure expenses, messy code, and AI hallucinations. Rather than replacing software engineers, AI is reshaping their role into one focused on supervision, integration, judgment, and system management.
