Paul Dix, Founder and CTO of InfluxData, writes on the InfluxData blog:

I attended and spoke at KubeCon EU. It was a massive event attended by around 4,700 people … However, I felt there was an underlying problem … everyone I spoke with was either an operator or an SRE. Where were all the application developers? Aren’t those the people that all this complex infrastructure is supposed to serve?

Which raised questions for Paul, like…

Is Kubernetes too complex?
Will it end up collapsing under the weight of its own complexity?
Will it fade away as OpenStack has seemed to since 2014?

And Paul walked away from KubeCon EU with this perspective:

Application developers would be better served by having a happy path to follow with the tools preselected … CNCF’s increasing complexity and broader reach might dilute the focus and brand of Kubernetes … I’m not sure what the answer might be to this or if I’m overblowing it, but from my perspective at the conference, it was like tool porn. Why bother with solving user problems when you can spend your entire career learning about and building new tools for infrastructure?
