Now I seriously don't know what's the point of hiring junior developers for any companies.

This PR is written by GPT4. The only thing I need to do is to describe my problem clearly to GPT4 and it writes the perfect code in minutes. I only need to give a handful reviews and GPT4 will satisfy me. It only costs me 20 USD / month.

If I were to let a junior developer to write this code, 2 problems:

1. They may not even understand my problem description because of lack of knowledge.

2. It will take them several hours and many back & forth code reviews to get it right.

The time efficiency is a 100X diff.

A junior developer also costs somewhere between 2000 USD / month - 5000 USD month depending on where you live.

Therefore, the time efficiency multiplied by the cost, the total efficiency is

10,000X - 25,000X diff.

I will never hire a junior dev again what so ever.
