A practical 2026 roadmap for modern AI search & RAG systems

I kept seeing RAG tutorials that stop at “vector DB + prompt” and break down in real systems.
I put together a roadmap that reflects how modern AI search actually works:
– semantic + hybrid retrieval (sparse + dense)
– explicit reranking layers
– query understanding & intent
– agentic RAG (query decomposition, multi-hop)
– data freshness & lifecycle
– grounding / hallucination control
– evaluation beyond “does it sound right”
– production concerns: latency, cost, access control
The focus is system design, not frameworks. Language-agnostic by default (Python just as a reference when needed).

Curious what people here think is still missing or overkill.

CMV: A second Mexican-American war would be national suicide.

Someone who understands contemporary US military capabilities, please disabuse me of some potentially bullshit assumptions.
Is Trump just planning a little drug bust with a few commandos somewhere in Mexico so he can get a photo-op for Fox? Otherwise, I can think of few better ways to end American hegemony forever than a second Mexican-American War, which I believe is almost certainly what we'll get if we send ground troops there. Mexico City is over 4X bigger, hundreds of miles further inland and 2.5X higher up than Caracas. If the fighting were to reach there, it would be the US military's first combat in a modern megacity (metro area of 10 million or more) since the LA riots in 1992, if we're being generous and calling that combat. If we're \*not\* being generous, it would be their first ever. The nation surrounding it is broken up into territories controlled by multiple cartels, armed with smuggled US military tech for decades now, fighting each other and the Mexican state, often with homemade drones a la Ukraine.
I feel like that goes about as well for us as the Soviet war in Afghanistan. You know how the CIA gave the Mujahideen stingers, javelins and bomb blueprints to destro
