I have quite a few talks on the disconnect we now have between OPS and DEV. Still in 2023 most developers haven't used an observability tool and don't even know what it means. Having played with Digma quite a bit I'm very hopeful that it will help change that for the better.
I think that such tools can revolutionize debugging issues quickly and as a result improve overall system reliability.
Observability should be a shared responsibility for R&D. Without that DevOps are chasing their tail and R&D is blind.
