Databases didn’t converge in 2025 — they diverged.

More engines, more specialization, more cloud lock-in, and more operational load pushed onto platform teams.

Go 1.26 brings the long-awaited vectorized operations (SIMD) in the simd/archsimd package.

Since it's hard to create a portable high-level API, the Go team decided to start with a low-level, architecture-specific one and support only amd64 for now.

Running Java/Jakarta EE on unikernels like Nanos challenges modern cloud assumptions.
Fewer layers, smaller attack surface, faster boot — especially relevant for serverless, edge, and cost-sensitive workloads.
Worth revisiting what we’ve taken for granted.
