@Wanda quoting myself below, what ever I said was just an opinion on this matter.
Elaborated version below mostly off topic but you need to know why? and how? when you want to understand this. Putting down what I feel regarding this, just one more opinion to the mix.
When I said that I had lots on my mind, I couldn't fit it all in my last post. Language is one of my core interests. Any language not English alone specifically. After all I own alphabet dot in(Which is going to be developed in future). Man buying domains is easy! developing them takes lot of effort but it is my interest and one can do only so many things at a time. We are not super humans at least I am not. My main intention was to preserve the alphabets of a endangered language(to begin with) and preserve it's literature so that in future an interested person can pick that up learn the language and teach to others interested. Everything is hypothetical
but I am honestly putting in an effort to make this possible. I will at least link to similar efforts if any so that alphabet dot in will at least be a resource.
I honestly think that English is not native language to my father or someone of his age(in 60's), but it is for me. I don't see it as a foreign language, it is native to me. Not because I am a Canadian, I felt so since I was a kid growing up in India. You see it as Foreign to us, not us. We see it as just another local language we all prefer to converse in communicate in. It is just like Hindi. It doesn't matter how well we use it, we JUST use it in our everyday activities. We are just comfortable in using it and is more natural to us than real native English speakers like you think. We mix English words in our conversations and this is also natural.
How many ever SIRI or other technologies popin they will not fill the GAP. They will only enhance the experience in local language but does not address the problem of intercommunication. If you wish SIRI or something like that to solve this issue, you have to add a layer of translation to SIRI which understands English that it hears and spits out Hindi translation which a native speaker can understand but this is too complex and is not a natural way we don't need this other than to deal with accessibility issues. The natural way is like how it is playing out now in real time in real India. Inter communication between people of India whose local language is unique for each of them is only possible with a universal language like English which will act as a common medium of communication(Verbal or Written). SO basically SIRI or something else is not a replacement for how usage of languages is naturally played out. Currently people across India are migrating all over internally and abroad because of employment trends or whatever English has a vital role to play more than ever. SIRI is not a wonder and not the only thing that does speech recognition, speech recognition technology is there for ages now. SIRI is an excellent implementation of the technology, I have to give it to Apple for that.
The way English is written by Indians(who are raised in India) has its own style and sub styles. These styles depend on individual person and their intellect. If you look at this post some of you might feel like 'this guy is taking us for a ride'. I can't be concise :|. Even native English speakers have their own writing style based on their intellect and choice but there is a basic writing style which looks same. We all use English for what it is - a universal language.
That said our major local languages will flourish for ages to come and developing technology will make this happen.
IDN investment as I see it is like..
If we look at stock investing there are good stocks and bad stocks. You invest in bad stocks you lose no argument here. IDN's are like bad stocks they are not investment grade. While I say that I also know people who did amazingly well and still going strong. IDN's are a niche investment if at all one wishes to invest.
Another analogy is if we buy mutual funds especially segregated funds(Canadian version of "Separate Account" of the US) You will never lose money why? it is because segregated funds are like below,
"A segregated fund is an investment fund that combines the growth potential of a mutual fund with the security of a life insurance policy. Segregated funds are often referred to as "mutual funds with an insurance policy wrapper"." - from Wikipedia.
So what I am trying to say here is you buy all the keyword domains which you think are widely used in Hindi and you will lose investment on the majority of them because not enough people will be typing in the url(will not try to think of using them, on most names you will see almost zero direct navigation traffic). This makes investors run away. Where as the English .in's and co.in's will see little natural traffic for popular keywords and other popular 2 or 3 word combos. These are like mutual funds you will make money here and there definitely and this is percieved as normal if you invest in real good names.
There will always be IDN's that get natural traffic and are en route to success. There are also the ones that are registered to develop and get developed they'll do well too. There will always the ones that are like wonders. This is not enough to put all the IDN's into investment pool and empty your pockets. That said I think domainers interested can still invest in a few of them and not put all their eggs in IDN basket.
