That remains to be seen. People who work with high-tech stuff can be hobbyists too. If we move on to e.g nebulizers, I don't doubt that some techy hobbyist may improve on the designs.
These are some interesting times with the dawn of home-based manufacturing like 3D printers and more affordable/available CNC equipment. Maybe the future revenue stream for current authentic manufacturers will be through designs, not products. Then again the designs would be even easier to copy.
If the innovators want to survive, they should take a business class before hyping their latest product.
The biggest problem I see is most of the "innovators" don't have a clue how to operate a business.
They have an idea, make a few pieces, hype them like they are a huge company when they don't even have a business address.
They have no business lisc, and operate through a Facebook account.
No matter what industry you are in, when the innovating players don't even have a contact phone and can't manufacture 1000 units, they are begging to be knocked off. It's not just vapes, it's not just China.
Modders are victims by their own design.
