I spend most of my time helping people use AI more. But today I want to talk about when to use it less.
Because here’s a truth that nobody selling AI tools wants to admit: there are things AI shouldn’t do. Things it’s bad at. Things where using it makes your life worse, not better.
Knowing the limits isn’t anti-AI. It’s pro-intelligence. The smartest AI users I know are the ones who know exactly when to lean on it and when to lean on themselves.
The Things AI Gets Wrong
Let’s start with the obvious stuff.
Facts and numbers. AI can and will make up statistics. It’ll cite studies that don’t exist. It’ll give you a date that’s off by a year. It’ll confidently tell you something that’s flatly incorrect.
This has gotten better over the last year. Models are more accurate than they used to be. But “more accurate” is not the same as “reliable.” If accuracy matters, which it does for anything involving money, health, legal matters, or public statements, you verify. Every time.
I’ve seen people include AI-generated statistics in business presentations without checking them. Don’t be that person. The embarrassment isn’t worth the time you saved.
Math. This surprises people, but AI is genuinely unreliable with complex math. Simple arithmetic is usually fine. But multi-step calculations, especially with percentages or unusual number combinations? Check with a calculator. AI sometimes hallucinates math the same way it hallucinates facts.
Anything requiring real-time information. Most AI models have a knowledge cutoff. They don’t know what happened yesterday unless they have web access turned on. And even with web access, the information can be incomplete or misinterpreted.
For current events, stock prices, weather, sports scores, or anything time-sensitive, use a real source. Your AI is working from a snapshot, not a live feed.
When Human Judgment Beats AI
AI processes information. Humans make judgments. There’s a difference, and it matters.
Ethical decisions. Should you fire the underperforming employee who’s going through a divorce? Should you tell your friend that their business idea isn’t going to work? Should you confront your neighbor about their dog?
AI can give you frameworks for thinking through these questions. It can present multiple perspectives. But the actual decision has to be yours. Because ethical decisions require understanding the full human context, the relationships, the emotions, the consequences you’ll live with. AI can inform the decision. It shouldn’t make it.
Emotional situations. When your friend is grieving, don’t send them an AI-written condolence message. When you’re writing wedding vows, do it yourself. When your kid is upset about something at school, be present. Don’t consult your AI about how to parent in that moment.
AI can help you process your own emotions through journaling prompts and reflection. But it can’t feel. And the people in your life can tell the difference between a message that came from your heart and one that came from a prompt.
Creative work that matters to you. If you’re writing a blog post for your business, AI drafts are great. If you’re writing a poem for your daughter’s birthday or a eulogy for your father, write it yourself.
Not because AI can’t produce decent creative work. It can. But because some things should carry the weight of your personal effort. The imperfection of your own words is more meaningful than the polish of generated text.
First impressions and relationship building. Don’t use AI to write your first message to a potential date. Don’t use it for your first email to a new client when it’s supposed to feel personal. Don’t use it for the thank-you note after a job interview where they specifically asked about your personality.
These moments matter because they’re human. The whole point is that YOU showed up. Using AI for the handshake defeats the purpose.
Where AI Makes Things Worse
There are some situations where using AI actively hurts you.
Learning new skills. If you’re trying to learn something, having AI do it for you is counterproductive. A student who uses AI to write their essay doesn’t learn to write. A programmer who lets AI generate all their code doesn’t learn to program.
Use AI to explain concepts. Use it to check your work. Use it to tutor you through problems. But don’t use it to skip the learning itself. The struggle is where the skill develops.
Decision fatigue (paradoxically). This is subtle. Some people start asking AI for every decision. What to eat. What to wear. What to watch. How to respond to a text. And instead of reducing decision fatigue, it creates a dependency that makes them less confident in their own judgment.
AI should handle operational decisions so you can focus on meaningful ones. Not handle all decisions so you don’t have to think at all. There’s a line, and it’s important.
Confidential or sensitive information. Your company’s unreleased product specs. Your client’s financial details. Your medical records with specific provider information. Your kids’ school names and daily schedules.
Some information is too sensitive for any external tool. Use AI for the general version. “Help me organize a report about Q2 sales trends” is fine. Pasting your actual company financials into a consumer AI tool might violate your NDA.
The Authenticity Question
Here’s one that’s personal for me.
AI can write in your voice. After enough context and training, it can produce content that sounds remarkably like you. And that raises a question: when does AI-assisted become AI-replaced?
There’s no universal answer. But here’s my line.
If I’m producing content for scale (weekly blog posts, email newsletters, social media) and the ideas, direction, and final review are mine, AI assistance is fine. It’s a tool, like a word processor.
If I’m communicating something deeply personal, something where the effort IS the message, I write it myself.
The question I ask: “Would the recipient care whether I wrote this myself?” If yes, I write it myself. If they just need the information or the value, AI assistance is fine.
You’ll find your own line. The important thing is to think about it, not just default to AI for everything because it’s easier.
A Practical Guide: AI or Not?
Here’s a quick reference for common tasks.
Use AI:
- Drafting emails (you review and edit)
- Research and summarization
- Meal planning and grocery lists
- Meeting preparation
- Goal tracking and accountability
- Routine scheduling
- Data organization
- Content outlines and first drafts
Think carefully:
- Client communications (match the context)
- Social media posts (make sure it’s your voice)
- Health advice (verify with professionals)
- Financial decisions (verify numbers, consult experts)
- Anything involving other people’s private information
Probably don’t use AI:
- Condolence messages and emotional support
- Wedding vows, love letters, personal poems
- Eulogies and tributes
- First impressions and handshake moments
- Ethical decisions (use it for perspective, not the decision)
- Learning something you need to actually understand
- Anything confidential to your employer
The Balanced Approach
The best AI users aren’t the ones who use it for everything. They’re the ones who use it for the right things.
They automate the operational. They delegate the repetitive. They keep the human stuff human.
That balance is what we teach at Achievementoring. Not just how to use AI, but when. Not just the capability, but the wisdom.
Because the point of having an AI system isn’t to become less human. It’s to free up more time to be MORE human. More present. More creative. More connected. If AI is making you less of any of those things, you’re using it wrong.
