Generative AI in strong images: what it can do, how it writes, why it convinces, how to use it well and where to take care.
Apps
What can generative AI do today? Around a glowing spark lie six powers: writing, painting, listening and speaking, translating, programming, discovering. A short wish breaks into particles of light and arranges itself into a finished result: a letter, a picture, text, a translation, a small app, a folded protein. For each power one limit and one counter-spell; watch or try it yourself.
Understanding AITry it
A sentence grows word by word: at its end the candidates for the next word float as spheres of light, the larger, the more likely. A courage dial (temperature) shows how the same beginning continues reliably or imaginatively, threads of light show attention to earlier words. An ocean of pages explains where the feel for language comes from.
Understanding AITry it
An AI answer as a splendid facade: every window axis is a sentence, all sound equally sure. Three counter-spells shine behind it (ask back, check the source, second opinion) and show for each sentence foundation, sand or stage set. Sound and support as a picture, four everyday answers and a traffic light for when checking matters most.
Understanding AITry it
A vague wish to the AI opens a wide fog of possible answers. Every building block in the spell condenses it until a clear beam hits the target: for whom, goal, role, example, form and limits. Four everyday cases with an example answer before and now, magic as a conversation in rounds and a counter-spell against private data in the spell.
Understanding AITry it
An AI agent as Goethe’s sorcerer’s apprentice: the broom gets a task and runs the glowing loop plan, act, check, correct. Every round carries a bucket to the goal, mistakes it finds itself. Three everyday tasks (farm-shop website, club party, train journey), a leash of approvals for money, sending and deleting, and a stranger’s note in the bucket.
Understanding AITry it
Amara’s observation as a picture: expectations of a new technology shoot up and fall back in disappointment, while the impact rises quietly and overtakes them. Railways, electricity, the internet, smartphones and AI today with sourced key dates and an open band for the future. Plus a scale with nine cards: what is overestimated and what is underestimated about AI, each with a counter-spell.
Understanding AITry it
The same AI can carry you like a sedan chair or train with you. Over eight weeks a plant grows by the path each week, as strong as your own strength: in learning (homework, Spanish), at work (quotes, care reports) and in decisions (medical findings, contracts). A lantern shows who holds the judgement, a sun the time saved.
