In the age of Transformers and neural nets that write poetry, it’s tempting to assume deep learning dominates every corner of AI. But in quantitative investing, the roots tell a different story. A recent paper—QuantBench: Benchmarking AI Methods for Quantitative Investment1—delivers a grounded reminder: tree-based models still outperform deep learning (DL) methods across key financial prediction tasks. ...
“Every technical revolution rewires the old system—but does it fry the whole board or just swap out the chips?” The enterprise tech stack is bracing for another seismic shift. At the heart of it lies a crucial question: Can today’s emerging AI models—agentic, modular, stream-driven—peacefully integrate with yesterday’s deterministic data flows, or will they inevitably upend them? The Legacy Backbone: Rigid Yet Reliable Enterprise data architecture is built on linear pipelines: extract, transform, load (ETL); batch jobs; pre-defined triggers. These pipelines are optimized for reliability, auditability, and control. Every data flow is modeled like a supply chain: predictable, slow-moving, and deeply interconnected with compliance and governance layers. ...
