While I agree with you here, but if you're doing a 9 hour work day with an hour on the shoulders for your commute, then you're looking at 19 hours dedicated to work alone.
Say, 30 minutes for dinner (if you're not the one cooking), 15 minutes for shower/grooming, 30 minutes for exercise plus whatever time it takes to get ready and cool down...so...an hour? If you're rolling solo, that probably rounds out your daily commitments. With kid(s) and a partner, you're down to 3 hours in which to help/bond with kids, spend time with your partner, plus whatever travel/wind up/wind down time those things take. Maybe 30 minutes a day you could really commit to these things?
I dunno, there are a lot of variables, but I find that prescriptive articles like these essentially dump the demands for your <insert here> project upon the shoulders of your family. If you want to make it really uncomfortable, consider the demographics of people here and in the software industry at a whole. Now it's just more of men offloading the work of family, house and home, etc. on the women in order for them to get their own projects done.
Sounds great, but don't expect much.
