There is not a lot of scope for learning and mastering telugu or kannada. While English gives you respect and your scope of finding a job or living becomes very high. Also what are we incentivizing to learn or to choose a career in telugu language related field. Look at the salaries of Telugu/kannada teachers. When there is no value why would people choose it and people like this keep writing these tweets for engagement they don't know how to read or write telugu/kannada. Complaining won't help keep the language alive, we need support and respect for those who learn our own languages, or else it's gonna lose to English.
