A lot of people are picking apart the many problematic parts of this, but I'll choose to target "Regurgitating content from the trending influencer of the week."

This is fundamentally how humans work. Our civilization is far too large and complex for you to be a bona fide expert in everything. And even worse, the more time you spend dedicated to expertise in one thing, the less well rounded you are in the ~infinity other things.

So what do you do if you cannot have authentic "taste" in everything?

You trust people. You find "influencers" that seem to succeed and have knowledge and you trust their opinion.

In practice, the vast majority of everything we think and do are not because of our personal expertise, but because of our un-expert belief in other people who do these things. Taste isn't just a measure of your personal expertise, but a measure of your ability to find and listen to experts.

So to call this out as a negative is harmful. You need to assemble a group of influencers not just professionally, but in every part of your life, who themselves are experts and can lend you their taste so you can make decisions without the paralysis of needing personal expertise in all things. That, or you need infinite time to become an infinite expert.
