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.

I am in my freshmen year of college, I was able to finish my 1st semester already, but no one prepared me from the ache that I will feel once the holiday break

I See God the Same Way I See Superheroes. As a Source of Hope, Not Proof.
I’m a young male and to me personally, God is like a superhero. I like Spider-Man, and I like God too. Both inspire me, give me hope, and help me get through tough moments. That doesn’t mean I believe they’re literally real.
When a Spider-Man movie comes out, I go watch it because I connect with the character and what he represents. In the same way, when there’s a God-related day, I visit spiritual places because I like the atmosphere, the meaning, and the sense of peace it gives me.
For me, it’s not about blind belief or denying logic. It’s about stories, symbols, and ideas that make life feel a little lighter and more hopeful. Just because something inspires you doesn’t mean you have to treat it as unquestionable truth sometimes it’s enough that it helps you live better.
