I'm sorry, I guess?
Typo aside, I did try to capture the essential difference of a server-side templating engine vs. how many people build using "modern" web stacks.
Yeah, this what makes me sad. Your premise is that SPA is the default for web development and you imply server side rendering is not “modern”.
Disclaimer: I don't like SPAs, and I think the "modern" web stack is a niche set of technologies that are being widely overused. (This is why I put "modern" in quotes.)
But I have worked with enough engineers schooled since React became popular to know that the "modern" Web stack basically is SPAs everywhere.
Incidentally, this same evolution has made SQL something of a dark art among programmers. It's good that the field is big and diverse and specialized! But also, there are tons of professional full-stack Web programmers who are functionally illiterate in SQL due to primarily using NoSQLs or ORMs.
