Google does not recommend rewriting dynamic URLs into static URLs

From the latest Google Webmaster BlogArticleLet's see, itNowStatic URLs are not encouraged.

Google mentioned the following points in the article.
1) there is no problem with static website indexing.
2) There is no problem with crawling the original dynamic web site Google spider.
3) Incorrect rewriting will only make it difficult for Google to capture webpages, so it is still necessary to maintain the original dynamic web site.
4) The number of dynamic URL parameters is no longer limited, But simplifying the URL is still the common goal of dynamic and static URLs.
5) If you want to simplify the dynamic URL, remove parameters irrelevant to the content.
6) Google recommends that you avoid rewriting dynamic URLs.

Google did not mention the following points, and these are what I think are more important.
1) is static websites advantageous in rankings?
This is not clear. Let's talk about it on Google.

2) How do users feel about static and dynamic websites?
I think there are some. When you search for a keyword, when the keyword appears in the URL, this part of the URL will be bold. It is related to the user experience and affects the click-through rate.

3) What should I do if I have repeated content in a dynamic website?
It is unknown whether Google will handle this part.
