Is quantitative trader becoming obsolete?

I've recently read many opinions that traders are becoming obsolete (Will Trading become obsolete? | Wall Street Oasis) (Who do you think has a better future - a quantitative researcher at hedge fund like Citadel or a proprietary trader at Jane Street? - Quora).

This seems to apply to traditional traders that manually trade being replaced by computers, rather than nowadays quantitative traders (which also do a lot of coding). Is this true?

If so, why do you think quantitative traders are still necessary? From what I understand quantitative researchers nowadays can develop the model and push that to production (with the help from tech engineers) to automatically execute trades. From this logic, I'm not sure where quantitative traders will fit in the process, especially with trading algorithms and technology becoming better everyday.
