For other readers Argo does support 'Scripts' which means you can implement complex logic similar to Airflow if required but can be a bit clumsy: https://argoproj.github.io/argo/examples/#scripts-results
Additionally, I think we may see other layers on top of Argo in future that may abstract from the YAML similar to how Kubeflow uses Argo for the Kubeflow Pipelines capability: https://www.kubeflow.org/docs/components/pipelines/pipelines...
