I read it as:
* Spend time empowering others to write production code * Reporting to line manager doesn’t mean not making decisions. * Spend time empowering others without having to always know the latest greatest new ways of solving a technical problem. * Meh, might be the circumstances * If this is “limited scope” in terms of qualified for a job, really depends on the company. If “limited scope” in terms of qualified to author this blog post, as has been observed by other commenters, this blog post is out of date and practices have changed since 2020. Pretty sure the practices 6.5 years before she wrote it were so vastly different that the 10-30 years of experience wouldn’t have been able to write a better or worse summary
The existence of her blog and willingness to talk about this stuff as a resource for the rest of us is pretty powerful evidence she’d bring value to a company.
But YMMV
