It is hard to say whether it will be lost altogether, I do think that standards are generally falling and that is mostly because the trade hasn't trained enough people to a high enough standard and those people are now passing those standards on. If people don't know what the real thing looks like, how can they make it? The biggest houses have let themselves down as far as quality goes for years, through a mixture of neglect and ego and they are mostly the only places training.
I also think that Savile Row has an image problem and is hopeless at PR. Having said all that, There are plenty of customers about and certain places on the street are very busy.
I am trying very hard to do my bit, I have a couple of young people working with me at the moment and I am doing my best to set a good example. I want to make the stuff as stylish and in as traditional a way as is possible.
