Multiple developers posted on the topic of vibe coding, where plain-language prompts generate app code. One noted the first 90 percent feels like magic while the last 10 percent shows why software engineering matters and that engineers remain important. Another stated knowing code is basic and that engineering involves more than writing it. A third warned that problems arise when builders do not understand what happens under the hood. A fourth added that fast shipping will later burden maintainers who did not write the original code.
