Tony, inventions don't often come from an established requirement like a DVDA codec.
Some smart people see a need before the need becomes a defined requirement.
Probably a bad example but Apple didn't respond to "request for portable music player" did they? They saw an opportunity and created the market.
If you look at hi-res music and the future of music streaming, then smart people would realise the issue and hence the need to solve the problem of large files vs bandwidth.
Similarly, people in the business have been worried about how best to digitally archive old tapes that will be degrading with more years spent in tins.
I suggest that just because a user, perhaps like yourself, didn't have a need for MQA doesn't mean that there wasn't one.
