Yes, people tend to seek new ideas to solve problems that may already have a good solution available. People are always looking to make things easier or to make money off something, so yes people do look to find new solutions to problems that already have viable solutions. It's all about convenience and money.
People are often searching for ways to solve a problem that already has a good solution to it. This behavior has been happening in the past and present a great deal. There seems to be an instinct in us to want to make something better, causing us to try and make a better solution to a problem.
Yes, people tend to seek new ideas to solve problems that may already have a good solution available, because people are creative and always want to find a better way. Although there may be a good solution available, another solution might be more efficient or better. It is natural for people to want better.
People tend to seek new ideas to solve problems that may already have a good solution available, and they do this constantly. In the corporate world, managers are always looking for ways to improve work flow. What they don't realize is that sometimes trying to improve a process destroys it all together. Leaving a solution as-is sometimes is best.
I don't believe that many people do seek new ideas to solve old problems that might have a good solution. There is that old adage "if it's isn't broke, don't fix it." However, there may be some entrepreneurial types out there who are looking to improve things that most people didn't even realize needed to be improved.
