# Here's why I don't agree with you: Tableau Conference 2026

> This is content from just-tim, the data-and-analytics channel by Tim Ngwena (formerly 'Tableau Tim'). Tim has 12+ years of hands-on BI experience and covers Tableau most of all, plus Power BI, Looker, Hex, SQL and data modelling, the analytics industry, and the craft of doing the job — always tool-agnostic and honest about the trade-offs.

## Key takeaways

- This year's main keynote deliberately showed only capabilities that had already shipped — a clear 'show, not tell' choice rather than a parade of new announcements.
- A useful rubric for judging any keynote: intent (the marketing/feeling the vendor wants to create) plus context (everything an individual brings to that moment) equals perspective.
- The reason opinions on TC2026 are so fractured is that the community no longer shares a context for where the industry, the field, or the product should go — AI has scrambled our shared best practices.
- Tableau's biggest weakness isn't ideas, it's shipping speed: composable data sources were discussed in 2024 and still aren't fully shipped, while Hex, Sigma, Omni and others ship monthly.
- Tableau's vast API landscape is both an advantage and an Achilles heel — in a world of MCPs there are no walled gardens, and rivals can pull data straight out.
