Petzi;

The simple answer is NO.

Lots of inventions are made that take millions to bring to market. It took about 10 years and that much money to bring out 2 electron sensitization and they are still perfecting it.

So, if the market is shrinking, they extrapolate to the 'end' and see if there is profit. If there is not, they cannot invest in it. They look for something that has more potential for profit.
