I share your concern for Tamil Language. But to survive, we ha ve learnt english. It is the cost we paid modernization. But tamil is living in villages, especially in farming communities, and supporting communities. It is also thecost we paid for scientific development. Also I worked in Central Government ( 20 years) in Delhi, rest on Chennai. I know well to write in Tamil. But , Tamil typing I don't know. These are the practical development. We should develop Tamil scientific vocabulary also. Thanks sir.
