All of it? Of course not. I just raised my children while also enjoying a demanding career, and utilized the best combination of additional resources I could find (spouse, nanny, day care) to get everything done well - or well enough. Like the med students on this forum who decide to have children will do.
My point is that there's a lot of parenting work that can be done by others without sacrificing much of anything that's truly important to a child's well-being -- like diapers between 7:30 am and 7:00 pm. I believe family mealtime is important, so made sure to be home to eat breakfast and dinner with my kids almost every night. Who cooked that meal was considerably less important, though I made sure both kids learned how to cook and often cook with them now. Helping with 'the hard homework' was something I considered important, so I had the afternoon teen babysitter help them get through the easy stuff and saved the hard stuff for myself. Bedtime stories were very important, so always Mom or Dad. Housecleaning and yard work? Outsourced all but the 'everyone should know how to' stuff -- Discussions about current affairs, politics, religion, values and the arts? Very important, frequent and in-depth. Reality TV -- not so much.
Did I 'cherry pick' parenting? You bet. And I raised some great kids.
