What is concurrency vs parallelism in Go?

Concurrency juggles tasks (goroutines switching), even single-core. Parallelism cranks multiple cores simultaneously. Go blurs 'em beautifully.

How does Go handle Event Sourcing with goroutines?

One goroutine per aggregate (like accounts) serializes events via channels. Prevents races, scales horizontally.

Will CQRS in Go replace my monolithic backend?

Not overnight — but pair it with clean separation, and yeah, it scales writes/reads independently like a dream. Word count: ~950.
