What is then terrifying to me then is when I find myself working with people who manage to, by way of treating "estimates" as "quotes", make it so demoralizing to plan anything--as it will be "used against you" later (which they do even if they were adamant they wouldn't)--that everyone does everything they can to discourage and sabotage any attempt at planning, because planning is valuable :(.
