Why LLMs struggle with analytics

Alright, gather 'round, folks, because I think we've just stumbled upon the single most profound revelation of the digital age: "LLMs are trained to interpret language, not data." Hold the phone, is that what they're doing? I was convinced they were miniature digital librarians meticulously indexing every last byte of your SQL tables. My sincere apologies to Captain Obvious; it seems someone's finally out-obvioused him. Truly, a Pulitzer-worthy insight right there, neatly tucked into a single, declarative sentence.

But fear not, for these deep thinkers aren't just here to state the painfully apparent! Oh no, they're on a vital quest to "bridge the gap between AI and data." Ah, "bridging the gap." That's peak corporate poetry, isn't it? It's what you say when you've identified a problem that's existed since the first punch card, but you need to make it sound like you're pioneering quantum entanglement for your next quarterly report. What is this elusive gap, exactly? Is it the one between your marketing department's hype and, you know, reality? Because that gap's usually a chasm, not a gentle stream in need of a quaint little footbridge.

And how, pray tell, do they plan to traverse this mighty chasm? By "obsessing over context, semantics, and performance." "Obsessing"! Not just "thinking about," or "addressing," or even "doing." No, no, we're talking full-blown, late-night, red-eyed, whiteboard-scribbling obsession with things that sound suspiciously like... wait for it... data modeling and ETL processes? Are you telling me that after two decades of "big data" and "data lakes" and "data swamps" and "data oceans," someone's finally realized that understanding what your data actually means and making sure it's fast is a good idea? It's like discovering oxygen, only they'll probably call it "OxyGenie" and sell it as a revolutionary AI-powered atmospheric optimization solution.

They're talking about "semantics" like it's some grand, unsolved philosophical riddle unique to large language models. Newsflash: "semantics" in data just means knowing if 'cust_id' is the same as 'customer_identifier' across your dozens of disjointed systems. That's not AI; that's just good old-fashioned data governance, or, as we used to call it, 'having your crap together.' And "performance"? Golly gee, you want your queries to run quickly? Send a memo to the CPU and tell it to hurry up, I suppose. This isn't groundbreaking; it's just polishing the same old data quality issues with a new LLM-shaped polish cloth and a marketing budget to make it sound like you're unveiling the secret of the universe.

So, what's the grand takeaway here? That the next "revolutionary" AI solution will involve... checking your data. Mark my words, in six months, some "AI-powered data contextualization platform" will launch, costing an arm and a leg, coming with a mandatory "obsessive data quality" consulting package, and ultimately just telling you that 'customer name' isn't always unique and your database needs an index. Truly, we are in the golden age of stating the obvious and charging a premium for it. I'm just waiting for the "AI-powered air-breathing optimization solution." Because, you know, breathing. It's all about the context.
