Sure, I can provide a summary of the article you provided. Here are three bullet points that summarize the key points:

• The article discusses how Shenron, the dragon from the Dragon Ball series, was unable to grant one specific wish due to technological advancements. In the original Dragon Ball series, Shenron had the ability to grant any wish, but in the modern era, there are some wishes that Shenron cannot fulfill due to the development of technology.

• The article cites the example of a wish to revive someone who has died. In the early Dragon Ball series, Shenron could easily bring a person back to life, but in the modern era, this wish has become more complicated due to advancements in technology, such as the ability to clone or create artificial life. The article suggests that Shenron may not be able to grant this wish in the same way as before.

• The article also mentions that Shenron's powers may have been limited by the creators of the Dragon Ball series to maintain a sense of tension and drama in the story. By making certain wishes impossible for Shenron to grant, the creators can introduce new challenges and obstacles for the characters to overcome, keeping the narrative engaging and unpredictable.
