a16z General Partner Andrew Chen kicked a hornet's nest last week. His post on X argued that AI code generation makes spreadsheets obsolete - and racked up over a million views in the process.

His core argument: spreadsheets are business logic trapped in a grid. Pricing models, financial forecasts, inventory trackers, marketing attribution - all fundamentally programs we've been writing in the worst possible IDE. No version control. No testing. No modularity. Just a fragile web of cell references that breaks when someone inserts a row.

The only reason spreadsheets won, Chen argues, is that the barrier to writing real software was too high. A finance analyst could learn =VLOOKUP in an afternoon but couldn't learn Python in a month. AI code generation flips that equation. Now that same analyst describes what they want in plain English and gets a real application - with a database, a UI, error handling, the works.

Not everyone agreed. Hundreds of replies pushed back hard. One of the sharpest counterpoints came from Dan Hockenmaier, who drew a line between two kinds of spreadsheet use:

Robert L. Peters offered a full defense from the front-office finance world: "One single calculation error can dramatically change the answer and cost you $1 million or $1 billion. 95% right is 0% useful." His point - that spreadsheets provide cell-level auditability that code and prompting can't yet match - landed with a lot of readers.

Chen's response was measured. He acknowledged the need for inspection and debugging, but argued those workflows migrate to a better substrate in software. Version control, unit tests, AI-assisted code review - all things spreadsheets simply don't have.

The takeaway: The debate isn't really about whether spreadsheets disappear entirely. It's about whether they remain the default way a billion people interact with data and business logic. For the "mini software" use cases - the trackers, the schedules, the operational workflows - the answer increasingly looks like no.

Here's where this debate hits close to home.

Hockenmaier's "mini software" category - dashboards, trackers, attribution models - perfectly describes how most training organizations run their operations today. The scheduling spreadsheet. The instructor availability tracker. The attendance log. The class feedback summary. The revenue report stitched together from three different tabs.

These aren't analytical tools people use to build understanding. They're operational workflows masquerading as spreadsheets. And they break constantly.

If you run training operations, you already know the pain. Scheduling a single instructor-led class can involve a dozen emails, a shared Google Sheet with conflicting edits, and a calendar invite that goes out too late. Multiply that across hundreds of classes, dozens of instructors, and multiple client accounts, and you have an entire operations team spending its time on logistics instead of growth.

The training industry is one of the clearest examples of Chen's argument in action. Training providers aren't using Excel and Google Sheets because the grid is the best interface for understanding their business. They're using spreadsheets because purpose-built training management software didn't exist - or was too expensive, too rigid, or too focused on content management (hello, LMS) instead of delivery operations.

That's changing. The same shift Chen describes - from "janky software you didn't realize you were building" to real applications with proper infrastructure - is exactly what's happening in training management. The spreadsheet that tracks your instructor roster, class schedule, and client communications isn't a spreadsheet problem. It's a software problem that's been waiting for the right solution.

Bottom line: If your training operations still live in spreadsheets, you're running "mini software" without version control, without automation, and without scale. Training management software is replacing these workflows - and the industry is moving fast.

You don't need to wait for AI to replace your spreadsheets one cell at a time. TryTami's training management software is purpose-built for the work training providers actually do - scheduling, instructor matching, logistics, communications, and reporting - all in one platform.

Launch a new instructor-led training class in under an hour. No spreadsheets. No email chains. No stitching together five tools to get one class out the door.
