A discussion that makes us think about the boundaries of what is or isn’t possible today is indulgence?

You failed spectacularly by your own definition of a good faith discussion by dismissing ops post as “fantasy”. You give no explanation of why it is unachievable today or why it would continue to be impossible in the future.

My previous team had a member who outright dismissed ideas and criticized things for the sake of sounding intelligent without proposing solutions to further the discussion or solve the problem. We let him go.

Good luck.
