why do you think it is popular nowadays?

To provide a specific answer, I would need to know exactly what you are referring to as "popular" nowadays. This could relate to a trend, a specific technology, a social movement, a type of media, or something else entirely. Popularity can often stem from factors such as accessibility, cultural relevance, technological advancements, social media influence, and current events.

If you can clarify what specific topic you're asking about, I’d be glad to help explain its contemporary popularity!
