Penna – Palar- Cauvery link canal UPSC NOTE

 Why in News

  • The public has come to view the AI  with mixed perceptions. 

  • AI has helped in monitoring heart problems and eye conditions and offered treatment options.

  • AI predicts protein structure and aids in the development of new drug molecules

  • Likewise, it predicts cyclones, monsoon strengths, etc.

  • On the dark side are fears that jobs may be lost to thinking machines that work 24/7 

  • But nobody doubts that AI will help us in addressing large-scale problems that require the analysis of huge data.

  • As India’s development gathers momentum, we are faced with the eventuality of resource limitations

  • We may need much more than we have. 

  • This is especially true of water—every year we see floods in parts of the country and drought in others. 

  • Engineers have long dreamt of building links between our rivers to mitigate these problems.

  • But uncertainties over the effects of such large-scale changes have stalled many initiatives.
