It means that you don't need a technician at all where the problem is completely automatable.
In the original blog post, the developer who was automated away was of that type - adding HTTP API endpoints from protobuf definitions if I read correctly.
It seems that you and the original blog post only disagree about what the word "technician" means (and I think I'm on "your side" with the definition). But the original blog post really talks about automating away developers who do things like writing HTTP API endpoints from protocol buffer definitions - with that I totally agree with.
