To put that another way: most people who call themselves data scientists do not have a PhD and have zero research publications.

False claims. There're as many who do and do you know what it does not matter for this discussion because data science and deep learning is a science independently of what some people do or not. This was the point.

Haha sure, read some papers about Bert and its successors. Come back and summarize what you have learned. But your comments shows so clearly that your opinion is set and politely you should check out data science and deep learning before you again write such shallow dismissals (which is against the guidelines btw).
