Genuinely good at

Modern assistants are remarkably capable at anything shaped like language in, language out:

• Transforming text — summarizing, rewriting, translating, changing tone or format.
• Drafting from scratch — emails, outlines, plans, stories, code. Beating the blank page is their superpower.
• Explaining — taking a dense topic and re-explaining it for a 10-year-old, an expert, or anyone in between.
• Structured thinking — brainstorming options, making checklists, comparing pros and cons.

For these, AI often takes you from zero to a solid first draft in seconds.

Be careful with

The same design that makes them fluent also creates predictable weak spots:

• Facts and figures — a model can state something false with total confidence. This is called a hallucination, and it's the single most important risk to understand.
• Recent events — anything after the training cutoff is a blind spot unless the tool can search the web.
• Math and precise counting — surprisingly shaky without a calculator or code tool, because it's predicting digits rather than computing them.
• Anything needing real accountability — medical, legal, and financial decisions need a qualified human in the loop.

Why it hallucinates, in one sentence

The model was trained to produce plausible text, and a confident-sounding wrong answer often looks more plausible than "I don't know" — so unless it's been carefully tuned, it fills the gap rather than admitting one.

How to get the best of it

• Ask it to show its reasoning or cite sources so you can check the work.
• Give it the source material instead of relying on its memory ("here's the contract — summarize clause 4").
• Treat every fact that matters as a claim to verify, not a settled answer.

Rule of thumb: AI is a brilliant, fast intern. Fantastic for drafts, explanations, and ideas — but you sign off on anything that actually matters.

Try this: Ask an assistant for "three quotes from a famous person about productivity, each with its source." Then check them. You'll likely find at least one that sounds perfect and never existed — a hallucination, live.
