most people calling themselves "AI engineers" know maybe 3 of these.

the actual top 1% skillset:
→ LLM inference
→ Agentic chatbots
→ Agent tools
→ Self-correcting loops
→ Autonomous loops
→ Debate models
→ Token efficiency
→ Agent harness
→ Memory
→ Context engineering
→ Context compactness
→ RPI loop
→ Subagent spawning
if half this list is unfamiliar.. that's your roadmap.
