There are many blog posts like this one that deny (often deride) the value of software craftmanship, including the skillset of planning.
They almost always have this same conclusiveness to them as well ("she was right"), with no tangible backing other than personal anecdata ("everyone sucked who I worked with, so everyone must suck").
If you zoom out, the reality is that people in the software industry are spoiled AF. A majority of practitioners get paid a ridiculous amount and get away with murder.
It is true that current market dynamics give people in this industry pretty much zero incentive to get good at the craft. So people don't and then to rhetorically justify their philistinism, they write blog posts like this.
It is also true that many businesses get away with writing absolutely shitty software and stay in business because of these dynamics. But that doesn't make it "ok" and doesn't say anything about the enormous amount lost to such apathy.
