TURING TEST DAYS · THE SIZING, TOP-DOWN · 2026 1 In 400 To 5,000 Digital Hours Goes To AI We Don't Know About All digital conversation hours · estimated 1.24T hrs 100% of all digital hours Email, Slack, messaging and DMs, worldwide: about 33 minutes per person online per day. 0.087% of the hours above Hours reading a message an AI drafted · assumed 1,083M hrs 0.087% of all digital hours 2.5T AI chats a year from ~0.6B daily users (all of whom know it is AI) × 6% write for someone else × 1.3 built into email apps × 20 sec a reader spends 90% of the hours above Of those, the reader was not told · assumed 975M hrs 0.078% of all digital hours KPMG: 57% of employees hide their AI use. 80% of the hours above Of those, the reader never noticed · assumed 780M hrs 0.063% of all digital hours Lab: AI passes 73%. Add 16M hours from bots and agents (OpenClaw, Hermes, Meta's business AIs): 796M hours ÷ 24 ≈ 30M Turing Test Days, about 90,000 years. A top-down view of our bottom-up sizing: the shares are implied by AI-chat volume (OpenAI, Alphabet, Meta), not measured on their own. Assumed = our number; nobody has measured it. Everyone who chats with AI knows it, so those chats are not counted.
