AI Hype Check: Why Traditional ML Still Powers Real Business in 2025
Not all “AI” is created equal—and enterprises know it.
A few weeks ago, I attended QlikConnect and spoke directly with practitioners about their real-world experiences with AI. The conversations underscored something that market data alone might not fully capture: despite all the buzz around large language models (LLMs), traditional machine learning (ML) still does the heavy lifting in enterprises.
At QlikConnect, practitioners shared how ML quietly delivers consistent, tangible business outcomes—from optimizing logistics to reducing customer churn—often without the fanfare LLMs typically receive.
📊 Market Size: Real vs. Hype
Consider this:
Traditional ML
**$93.95B in 2025 → $1,407.65B by 2034 (~35.09% CAGR)**¹
LLMs
**$7.77B in 2025 → $123.09B by 2034 (~35.92% CAGR)**²
These numbers highlight a stark contrast between actual adoption and public attention.
💼 Real Stories from Practitioners
Why do businesses continue to invest heavily in traditional ML?
Cost-effective & Scalable: Practitioners emphasized ML’s ease of deployment on existing infrastructure and the accessibility of platforms like AWS, which remains the leading cloud provider for ML workloads, with reports indicating a continued strong preference (around 59%) among ML professionals³.
Proven ROI:
By 2025, nearly 60% of hospitals in the United States have adopted at least one AI-assisted predictive tool in routine clinical care⁴.
Netflix’s widely cited ML-driven recommendation engine continues to deliver substantial value, estimated at $1 billion per year in churn reduction and enhanced user engagement⁵.
Explainability & Trust: Practitioners at QlikConnect highlighted ML’s advantage in regulated industries due to interpretability tools like SHAP and LIME.
🤖 LLMs: Great in Theory, Tougher in Practice
While excitement around LLMs was palpable, practitioners were quick to share their challenges:
Strengths: Undeniably powerful for NLP tasks; chatbots and virtual assistants, for example, represent a significant market segment, with the LLM chatbot market estimated at $5 billion in 2025⁶.
Practical Hurdles:
High deployment costs and significant compute demands.
Issues with output reliability, including hallucinations and biases.
Gallup’s latest findings (June 2025) indicate that 27% of white-collar employees report frequently using AI at work⁷. While this represents an increase from previous years, the findings also highlight challenges such as unclear use cases and value propositions, hindering broader adoption.
Scale ≠ Results: Despite impressive consumer-level statistics like ChatGPT’s 5.24 billion monthly visits (May 2025), and growing enterprise adoption (e.g., over 1.5 million enterprise users as of March 2025), enterprise deployment for core, scaled production workloads often remains predominantly experimental⁸.
🔍 The Hype Paradox in Action
Vendors frequently label everything "AI-powered," yet many LLM initiatives stall in prolonged pilot phases. Meanwhile, ML continues to quietly deliver on essential enterprise needs such as fraud detection, customer retention, and supply chain optimization.
🏁 Bottom Line: ML Wins on Practicality and Reliability
In 2025, traditional ML continues to offer the most reliable, explainable, and cost-effective AI solutions for real-world business challenges. While LLMs hold significant potential, practitioners at events like QlikConnect consistently emphasize ML’s reliability and ROI.
👉 I'm curious—where does your experience fall? Are traditional ML’s reliable results more valuable, or do you see LLMs overcoming their practical barriers soon? Let’s discuss!
