It's like a project manager without a nuanced understanding of software. Their skills are sending emails and scheduling meetings. The developer is the one that ends up building the project through technical know-how.
To think linguistically means to have no idea how anything actually works. You're intellectually or creatively incapable of doing the thing you claim to know. The one thing you are capable of is bullshitting without accountability. There needs to be technical knowledge, with a linguistic approach. Otherwise, you'd end up as someone who thinks that scheduling meetings are a skill.
