I help professionals & teams build real-world AI skills that actually make business impact.

Real-World AI in 2025.

Will You Be Ready?

“Python in Excel is intended to empower everyone (and we mean everyone now that we also have Copilot in Excel with Python) to do data analysis in an easy, secure, and compliant way.”

-Keyur Patel, Microsoft Principal Program Manager

AI is Being Sold Like It’s Magic

Microsoft will be like every other AI vendor out there - promising that Copilot will magically transform your organization:

  • Everyone in the organization with Copilot in Excel can perform amazing data analyses.

  • Better yet, with Copilot in Excel, everyone can harness the power of Python to perform advanced analytics.

  • Best of all, with Copilot in Excel, nobody needs to understand analytics, and they don’t need to know Python!

What Microsoft Won’t Tell Your Executives

The technical term for this is "hallucinations."

Sam Altman, the CEO of the most famous AI company (OpenAI), stated that hallucinations are more a feature of AI than a bug.

Think about this for a second. What Sam Altman is saying is that hallucinations are inherent in every AI. There’s nothing you can do about it.

Every AI will sometimes make stuff up at random.

Copilot will make mistakes.
Sometimes, Copilot will even make up stuff out of thin air!

How You Own AI

Because AI hallucinates, you still need a human in the loop to validate what Copilot produces. If you don’t do this, you’re playing with 🔥.

That’s the bad news.

Here’s the good news.

With DIY data science skills, AI technologies will allow you to do data science faster.
