I find it interesting . I know a lot of people who have written textbooks, but approximately none of them have made reasonable money at it. So if you could halve the time to produce a good one it would help, even better if you quarter it. But you are still probably losing money on your time relative to other things you could do. So why do it ? Mostly because it (the book) doesn’t exist. If 3 crap versions exist , I don’t know if you would bother .
