AI Makes You Faster(?) - What LLMs Actually Are and Why It Matters

Proposed session for SQLBits 2026

TL; DR

Large Language Models have become ubiquitous in our workflows with remarkable speed, already embedded in every application from Outlook to notepad. But just as sugar transformed from luxury to infrastructure before we understood its metabolic impact, AI is reshaping human cognition faster than we can measure the consequences. This session strips away the marketing hype to reveal what LLMs actually are: sophisticated pattern-matching engines that cannot distinguish between instructions and data. We'll examine hard evidence from recent studies showing measurable cognitive decline after just four months of regular use, and explore why developers consistently believe they're 20% faster while objective measurements show they're 19% slower. You'll learn about the fundamental architectural flaw that allowed journalists to bankrupt an AI-powered vending machine in three weeks, why every document in your knowledge base is a potential security risk, and what's happening to the generation of junior developers whose employment has dropped 20% since 2022. Most importantly, you'll leave with a practical framework for using these tools without outsourcing your ability to think. Unlike sugar, which affects our bodies, AI affects something far more fundamental: our minds. And we only get one shot at this.

Roche's Maxim of Data Transformation - By Example
Roche's Maxim of Data Transformation states that "data should be transformed as far upstream as possible, and as far downstream as necessary". Simple, powerful, and beautiful - but what does it really MEAN? Come find out through example.
 
Stand Fast - How Governance Can Save You a Fortune
Why is it that cloud projects often end up way more expensive than they should? The answer might surprise you: a lack of governance. Come learn how to turn governance from limitation to enablement.

The Untruthful Art - Five Ways of Misrepresenting Data
In this age of information it is imperative to be able to be able to clearly, simply and accurately explain and communicate sometimes complex data.
 
+5 Wisdom - Learn to Ask Better Questions to Solve the Right Problems
By asking the right questions we can solve the actual problem - not only the problem we think we are facing. Take a step back, look further, and ask better questions. We'll show you how.
 
Spell of Transmutation - Using Debezium to Transfer Realtime Data Changes to Event Hub
