This is generally correct about ALL technologies. You should NEVER start with a solution and look for a problem except in a very general sense (e.g. looking for potential markets in the abstract). Taking a solution market without having the problem well defined and identified is absolutely Epic Fail.

Once you think you have a market, you should see how it can be done FIRST without your "fancy miracle technology" because NOBODY buys a technology because it's sexy or trendy: they buy because it added value in terms of more capability or lower costs.

And ALL problems have current solutions that almost certainly DO NOT use anything as complex as your technology solution so you have to trend very carefully and deliberately in a rational sense: what value are we REALLY adding? That starts with knowing your competition and the current solution to solving the problem first and then finding every reason why your technology won't work or will be problematic.

You ONLY have market potential once you've exhausted those faults or have objective arguments for your value proposition that have been validated by actual customers. The actual prove is made when they are willing to write a PO to you for the solution. Until then, everything you are doing is unproven.
