How to broadly assess the state of research for a topic?
You can use any academic search engines such as Google Scholar, Microsoft Academic, or LENS (these three are freely available) or scientific databases such as Web of Science, Scopus, or Dimensions (these three require an [institutional] access for full use) and limit the time range of publications to the past years.
You could also add the word 'review' or 'survey' to your query, or, better yet, limit the search results to the document type 'Review' in order to specifically fetch articles that serve as reviews of a given research field.
