> So you think it’s reasonable to have no idea what it will cost, or when it will be done, when building software? You think it’s possible to run a successful business that way?

It absolutely is; look at some of the biggest and most successful software companies in the world. No-one has any idea what facebook will cost or when it will be done (Zuckerberg has said that he was off by at least 5 orders of magnitude IIRC). No-one has any idea what google will cost or when it will be done. No-one has any idea what amazon will cost or when it will be done. No-one has any idea what netflix will cost or when it will be done.

Google and Facebook are companies. They aren’t features. I know a lot of people at both companies, and they absolutely gave dates and estimation for many things.

You can have some idea, but it’s not like estimating the time and cost of building a house.

I’ve built major resorts, they are far more similar than people realize.
