Heh. Indeed. Only an idiot would be born into a family without a strong professional network ;-)
Less sardonically, I did have this option after high school (although not through a family network). Fortunately, I took full advantage before finishing school and did a ton of freelancing plus an internship. I noticed, before it was too late, that the sort of software engineering work available without a degree was not going to keep me happy for 30+ years.
This is the advice I give bright young students (as opposed to those who merely have family connections): make certain that you're not going to become unbelievably bored by your late 20s.
If you can get a job doing web dev out of high school, you can land a job doing something super fun like self-driving after college and you can write your own job description with a phd.
Your advice is good for kinda dumb kids from well-networked families, but IMO terrible advice for actually really intelligent kids. They will become super bored with the sort of software development that's available without spending a few years getting a good university-level grounding in mathematics and natural sciences. You can do that without going to college but it's still a four-year full time job...

I think you'd be disappointed; Google hires a ton of Ph.Ds and recruits heavily from tippy-top universities.
