It’s safe to assume that the viable market demand is already met by existing products.

By ‘viable’ I mean that companies can charge enough to remain in business by catering to a market segment that is willing and able to pay for the differentiation at margins sufficient to maintain the boutique sales channels necessary for low volume specialty goods.

Basically it is analogous to the audiophile market where discerning listeners are expected to pony up thousands of dollars on each piece of gear.

That’s my take.

YMMV.
