dravidian

Regarding the linked paper, there is no concrete evidence that Harappan was a Dravidian language.

Kannada is no harder to learn to learn than any other Dravidian or Indo-european languages.

Also, mama = Uncle in many Indian languages (both Dravidian and Indo-European).

None of the major Indian languages I'm familiar with have 4 nasal phones, from either the Indo-Aryan or Dravidian language families.

No mention of the hypothesis about Dravidian being descended from Elamite?

I learned Sanskrit as a kid and I’m familiar with Dravidian languages as well.

Do you really think that everyone who might hold the Aryan invasion hypothesis automatically thinks Indians are bovine Hindu Dravidian stock who never stand up for themselves?

There were a great number of Vijayanagara-era migrations, but sadly the South Dravidian languages have relatively less comparative linguistic study, so it's hard to say any further.

If the script is a full writing system, and I were forced to guess what a future decipherment might find, it wouldn't surprise me to see that the language is related to the Dravidian languages.

Although there are no attestations of Dravidian languages before 5th C BCE, we never know what future discoveries might tell about its connection to IVC, if any.

Kannada Primarily spoken in: India # of speakers: 38 million Language family: Dravidian Writing sample: ದಯವಿಟ್ಟು ಕನ್ನಡ ವಿಕಿಪೀಡಿಯದಲ್ಲಿ ಕನ್ನಡ ಲಿಪಿಯಲ್ಲಿ ಮಾತ್ರ ಬರೆಯಿರಿ Is awesome because: Reduplication!

While it is possible that for speakers of Indo-Aryan languages hindi is probably easier to pick up, that says nothing of the ease of learning the language for the majority of Dravidian language speakers.

Try telling that to the Jaipuris or the Marathas for starters (very Dravidian, those two).

South Indian languages like Telugu and Tamil are from a completely different family (Dravidian).

Very few non-Dravidian languages spoken in India, have that specific sound.
