You bring up Concourse comparision every single jenkins thread.
I've considered it the past but looked like there is almost no adoption outside pivotal. would you say the adoption increasing in 2018, I would like to give it another spin if possible.
Because it's the reference point I know best. It would be silly of me to compare it to microbiology or the internals of Travis, both of which I'm much less familiar with than Concourse.

It's nowhere near as popular as Jenkins, by at least 2 orders of magnitude, maybe 3. If that is important to you, wait a bit.
For example, resources are really nice, but there are a ton of pain points to do with how intentionally crippled the yaml pipeline format is (and in general how much repetition there is, due to the lack of looping, etc). Also the way i've seen people write pipelines tends to end badly for all involved.
Also its just very very buggy, especially if you deploy sans bosh, since thats basically not tested.
Switching the execution engine to Kubernetes will help a lot with operational pain. But consider the comparison to Concourse, which also predates Kubernetes. What drove Concourse into being wasn't the lack of Kubernetes (being born during the Diego project, itself a container scheduler), it was the amount of time and pain and unsafety that came from relying on the status quo.
Kawaguchi's agenda is bold and necessary, but I think it's going to take a while to get through even half of it. But the world is better off when Jenkins improves, simply because of its phenomenal installation base. We all talk about Travis and Circle and Drone and Concourse and Gitlab here, but I would bet folding money that over 75% of actual bits going through CI are going through some version of Jenkins.
Disclosure: I work for Pivotal, we sponsor Concourse.
