Digital marketing is automated now

Technical SEO can be managed using tools, so there is no need for a digital marketer for that. However, I have seen ads for backlinks creation offering 300 backlinks for just $1. Content writing and email marketing can be effectively done with the help of AI. I mean that basic tasks can be handled by existing employees, but if companies want to execute these tasks more effectively, they will need a digital marketing consultant. Let me know guys your thoughts?
