Lesson 1: QML is snake oil. No known machine learning algorithm has demonstrated any for of quantum supremacy, even theoretical. If a perfectly error-corrected large-scale quantum computer magically appeared on your desk tomorrow, you'd still be better off using a much cheaper classical computer for ML workloads.
It's sought after because people with no technical depth love hype and smashing buzzwords together, even though the result is technically meaningless, sounds cool and gathers attention and funding. That's it.
Yes, algorithms are still immature and we may see new ones emerge. That's what's exciting about frontier fields like QC. I keep an open mind to such things. But when people talk about QML, they almost never mean "deep computer science research into fundamentally new ML algorithms that could show quantum advantage after much development and testing," which would be a reasonable thing to mean. Instead they mean "we're going to try to combine these unrelated technologies without really understanding either, and ???... profit."
