Why LLMs Keep Missing This One Thing | Jason Ganz

The AI Native Dev - from Copilot today to AI Native Software Development tomorrow

Can LLMs replace structured systems to scale enterprises?
Jason Ganz, Senior Manager DX at dbt Labs, joins Simon Maple to unpack why, despite the rapid rise of AI systems, enterprises still rely on structured data for consistency and reliable decision making.
They also discuss:

• the invisible edge cases LLMs can’t see
• difference between software engineering and data engineering in AI
• the mismatch between AI output and business logic
• what the data engineer of the future actually does
