What it can't do (and shouldn't)

A confident owner is not the one who thinks AI can do everything. It is the one who knows exactly where the tool ends. Knowing what to keep away from AI is what lets you trust it with the rest. So this lesson is the honest other half: the jobs it cannot do, and the jobs it should not do even though it can have a go.

Can’t: things outside words

Remember the model. It is an assistant for words. Push it past that and it struggles.

• It cannot reliably do maths or precise numbers. It is a language tool, not a calculator. It can get sums wrong and state the wrong total with a straight face. For anything that has to add up, use a spreadsheet or your real system and let AI handle the words around the numbers, not the numbers themselves.
• It does not truly know today’s facts. It learned from text up to a point in time, and it does not have live knowledge of prices, news or availability unless a tool is specifically feeding it that. Ask it what is in stock today and it will guess.
• It cannot see your business. No access to your accounts, your calendar, your customer list or your policies, unless you or a proper integration give it that. On its own it is working blind about you.

Shouldn’t: things you can hand over but mustn’t

This is the more important list, because here the AI will produce something confident and usable-looking, which is exactly what makes it tempting to trust. Do not.

• Final decisions. Who to hire, whether to take a contract, how to handle a struggling member of staff. It can help you think, list the pros and cons, play devil’s advocate. It must not make the call. That is yours.
• Anything legal, financial or regulated as the last word. It can help you understand a contract or draft a first version, but a solicitor or accountant signs it off. AI is general guidance, not professional advice, and it is not accountable when it is wrong. You are.
• Sensitive personal or customer data pasted into a public tool. Treat a free chatbot like a public place. Do not paste customer records, card details, passwords or anything confidential into one. Strip out or anonymise the sensitive bits first. There is a whole later course on doing this safely across a team.
• Speaking to customers unsupervised. Letting an AI reply to real customers with nobody checking is how a business ends up apologising for something it never meant to say. Keep a human between the AI and the customer.
• Your genuine expertise and relationships. Customers buy your judgement, your reputation and your care. An AI can draft the words. It cannot be the reason someone trusts you. Do not outsource the thing that is actually your business.

The line to hold

There is a clean way to remember all of this. AI is brilliant at the first draft and the busywork. It is poor at the final call and the facts about you.

Keep it on the first-draft side of that line and it is one of the most useful tools you will ever pick up. Push it across to the final-call side and hope it works out, and sooner or later it will not. Confidence is not thinking the tool has no limits. It is knowing precisely where they are, so you can lean on the strengths without falling through the gaps.

Next we clear out the myths that stop owners even getting this far, because a fair few of them are simply not true.
