🚀 Emerging Tech & Trends (2026): awareness → selective depth
| Trend | What to know | Depth |
|---|---|---|
| Agentic AI + MCP + A2A | Tools, protocols, safety, durable agents | 🔴 Deep (Phase 5) |
| Context engineering | Managing what goes into the model’s context: retrieval, memory, compaction | 🔴 Deep |
| AI-assisted development | Using coding agents productively; reviewing AI code; spec-driven development | 🔴 Daily practice |
| LLM gateways & FinOps for AI | Routing, quotas, caching, cost per request | 🟠 Medium |
| Durable execution (Temporal, Restate) | Reliable long-running workflows | 🟠 Medium |
| Platform engineering / IDPs | Backstage, golden paths, self-service infra | 🟡 Awareness |
| Kubernetes Gateway API | Replaces Ingress | 🟠 Medium |
| eBPF | Cilium, observability, security without sidecars | 🟡 Awareness |
| Sidecar-less mesh (Istio ambient) | Cheaper mTLS | 🟡 Awareness |
| Java: virtual threads, structured concurrency, Valhalla, Leyden, GraalVM | Modern JVM performance | 🟠 Medium |
| Go: generics, iterators, PGO | Modern Go | 🟠 Medium |
| Lakehouse (Iceberg) + real-time OLAP (ClickHouse) | Data architecture | 🟡 Awareness |
| Vector search inside general DBs (pgvector, OpenSearch) | You often don’t need a separate vector DB | 🟠 Medium |
| WebAssembly on the server (WASI, Envoy/proxy filters) | Plugins, edge compute | 🟡 Awareness |
| Supply chain security (SLSA, Sigstore, SBOM) | Increasingly expected | 🟠 Medium |
| Passkeys / WebAuthn | Passwordless auth | 🟡 Awareness |
| Post-quantum TLS | Hybrid key exchange rollout | 🟡 Awareness |
