Wills should be written with the view that it will fulfill your wishes, in the most tax efficient way possible, whether you die tomorrow or in 50 years time. It should consider, then, what your situation looks like in 50 years. You may not have kids now, but in 50 years you might have children and grandchildren. Even if you don't have much assets now, you probably will in 50 years.
You have to assume that the will won't be updated before you die. Sure, you're supposed to update your will every time there's an event like marriage, children, etc, but few people do.
