Why not less focused work over more years? The argument makes zero sense to me.

Of course a lot of study and also applying what you learned are important. But having a PhD says very little about a person's ability to do data science or machine learning work. Especially since most phds have an extreme focus on their narrow field.

Deep learning resurgence is hardly 4-5 year old. Also to become an expert you need more focused work.
