Speaker who delivered a wroclove.rb 2025 lightning talk introducing OpenTelemetry to the Ruby community. Frames OTel as the emerging standard that most observability vendors are migrating toward, explains spans/events/traces as facets of a unified 'wide event' with high cardinality and dimensionality, and praises schemaless databases for telemetry. Says the Ruby OpenTelemetry libraries are still immature (logging is experimental) but encourages adoption anyway.
