The book

# published — available in English and French, worldwide on Amazon.

Book cover: Learn AI Now or Fall Behind — Practical workflows to stay relevant at work, by Sylvain Tissier
Name

Learn AI Now or Fall Behind — practical workflows to stay relevant at work

[FR] « Adoptez l'IA maintenant ou restez derrière » — édition française disponible.

Synopsis

Most AI advice is hype or prompt lists. This book teaches workflows — how to turn AI into leverage without sacrificing quality.

Options
  • pick the right execution model per task — not every job deserves the same loop.
  • install trust gates — so “fluent wrong” never ships.
  • build reusable assets that compound — workflows, not one-off prompts.
  • prove value with evidence — show the receipts, not the vibes.
“AI doesn't replace standards. It multiplies them.”
