The most probable outcome from the improvement of synthetic biology will be better medicines and medical treatments. With the ability to alter the DNA with tools such as CRISPER we are already able to stop certain defects that form in a womb. Scientists are already using CRISPR to try and help make antibiotics that can fight off bacteria that have become resilient to traditional antibiotics like penicillin.
People will also in the near future try to use CRISPR to make simple cosmetic changes to their appearance rather than have an actual medical need for its use. Since this technology is coexisting with the social media age where especially young people are more prone to compare themselves to others and be self-conscious it can lead to an increase of people just randomly deciding to get an eye color changed. Though in the near future only the wealthy who have the resources to afford this surgery would get it. Similar to how plastic surgery is today.
Another probable solution we will see play out is the introduction of bacteria into our oceans to eat plastic. This would help greatly in cleaning the ecosystems of our oceans which in turn would help with lessening the effects of climate change. There are also many other environmental-based projects which once complete will help clean ecosystems or help protect and recreate ozone layers.
Plausible (5 years from now)
A scenario that is plausible is an attack from a terror organization using a bioweapon made from synthetic biology. For example, imagine if somehow terrorists get a hold of a COVID-19 DNA and alter it to be even worse. This can be done by using a CRISPR machine and DNA of a virus or bacteria and just altering its DNA to make it stronger or more contagious. This deadlier version of COVID can then be released into a major city like New York City and it can slowly spread throughout the country increasing the time of the pandemic, more deaths of COVID-19, and a hurt US economy. These organizations also may try to copy already existing bioweapons made by militaries. Terror groups would justify attacking civilizations with these weapons due to ideological motives. In the future countries will need to start preparing for a potential bioweapon with preventative measures and solutions if one were to occur in a major city.
Another plausible scenario is the reintroduction of extinct species. One species this is possible with is the neanderthal as one scientist claims that all that is needed now to make one is willing human mother for it. Doing this would bring in many ethical considerations and some people would ask if science is going too far by reintroducing a species that could not survive naturally. The only valid reason to pursue an idea like this would be the sake of science as there is so much, we do not know about extinct species, and cloning one is the closest thing we can get to see a natural one.
Possible (15 years from now)
A possible solution we also can see in the future is the idea of reproducing human organs in order to help replace kidneys and other organs. Imagine a future where an eye can be reproduced for example and switched out with your own. This can have a major impact on those who have a vision disorder. It would also make it so people would not have to donate functioning organs as the ability to make just as good synthetic ones would be easier to make and more practical than asking someone to give up a kidney.
Biocomputers are improving similarly to how electronic computers developed during the 20th century whereas more time goes on the new computers are much smaller and faster than they were years before. This is possible because we will see improvements in the near future and will be more than just a niche form of computing due to their potential. This is because of how much less power is needed for a biocomputer to run instead of off electronics. This can help to put computers in areas in which power is scarce, save money on power bills, and help reduce a carbon footprint. Another big benefit of biocomputers is that they can be designed to reproduce on their own. Implications of this are that we can have biocomputers easily reproduce themselves without the need for typical manufacturing and lowering the cost of producing a new biocomputer. The reason why being the only thing necessary for a biocomputer to reproduce is it needs to be alive.
