[gotcha] Non-streaming AI responses feel slower and less trustworthy than streaming even when they arrive sooner

Always stream AI responses in user-facing products; if you must buffer for safety checks or structured output, show progressive skeleton or placeholder UI during generation to maintain perceived responsiveness and visible effort

Journey Context:
Counter-intuitively, a complete response appearing after 3 seconds feels slower and less trustworthy than one that streams over 5 seconds. Users associate progressive output with deliberation and effort, while instant complete output feels cached, low-effort, or suspicious. This is the labor illusion—people value visible effort. If you must buffer for JSON parsing, content moderation, or structured output, use skeleton UI patterns: typing indicators, progressive section headers, or shimmer placeholders. Never let the UI go completely blank during AI generation.
