The are some things that are technically very difficult if you have no domain expertise, which applies to the subject matter. Most people that try to do this without experience fail in practice, it takes a lot of time and effort to become competent at it, but once you figure it out it is repeatable without too much effort.

There is a much smaller set of things that are technically difficult to execute even if you are highly experienced at doing it -- each time is a challenge. This is not one of those cases, it just has a severe learning curve.
