But there won’t be just one person who is good at modifying fruit, it will be many. With the take over of all jobs by information technology everyone will have the time to try their hand at everything. Think of a city like Los Angeles with it’s population of millions. We think of talent in a field as being rare, but that is only because only a small percentage of the population get the chance. With everyone in Los Angeles with the time and the ability to do whatever they want the creative flowering will be immense. If they want a sweeter fruit they can do it themselves, or get the neighbour down the road to do it.
Then your entrepreneur is going to be up against those who are quite happy to do it for free; why shouldn’t they, it doesn’t cost anything and a sweeter fruit isn’t going to be that difficult to create.
In addition how much longer can patent and copyright exist with information technology. In a world where everything has virtually no value the need for it will disappear, and since everything has virtually no value there will be no profit and therefore no corporations to enforce this restriction of freedom. That will definitely be an improvement.
Capitalism first developed about 300 years ago. Everything that has a beginning must have an end and all the signs are that capitalism is starting to fall apart. By now we should be well into the fifth Konratief Wave, but it isn’t happening. And nobody can see any way that this current position of low growth and stagnation will finish. Which isn’t surprising as information technology must inevitably destroy all value.
What will replace it we can only guess at. Those in the feudal system of duty and obligation were never able to imagine how the capitalist system of markets and capital would work. In the same way we find it difficult to see how a post capitalist world would work, but we can be pretty sure that terms like capital and market are going to be largely redundant in the same way as duty and obligation between king, lord and peasant is redundant.
