It’s scary how fast technology develops, even scarier that I find it hard to imagine what would be invented or discovered next. The article I chose to read talks about the development of biological molecules which are basically made up of living organisms that can operate with its biochemical environment. It can also work by being within a living organism where it can interact with that specific environment by biological molecules inputs and outputs. The example given in the article interested me the most and it painted a clear image of its potential. The biological molecules can be used as autonomous(existing and functioning as an independent organism) “doctor” which is placed in a cell(in this case humans) where it can send signals from the environment for any possible threat of disease. It could then process signals by using its pre-programmed medical knowledge and output signals.Sounds all very fancy, seems like an opportunity to perhaps lead a more health friendly and health aware life.


However with this development, there comes the issue whether this advanced technology exceeds the limits of our natural being. Is this good or bad? This question is open to discussion which is necessary because only then we can benefit from science the way we would like to. Some people may think that biological computers can be relief as they have their bodies under the control of computers which in today’s world is more trusted than humans, whereas others may feel that they would not have control over and the comfort of their natural biological bodies.Therefore this issue can be tackled with these aspects; advantages being that you do not have to go to checkups or worry about threatening the health of your heart by eating extra fried and salted beef with chips( the biological computer will either help to balance your blood pressure that will explode after the meal or warn you).

It can be a support to your immunity system. Overall it can deal with minor body and health problems.Disadvantages, also can be stated as ethical and social issues is that it is a computer based system: not natural. Although it can come in handy some may not like the fact that their cells are given signals by these biological molecules. Another disadvantage I think is very important is that although it is new at the moment it is hard to predict the threat it may bring but as we experience daily, technology grows and spreads. If this technology was to spread and used by majority it would be likely that these molecules can take control over our lives. We may become so dependant that we would not even be able to imagine life without these biological computers.

There is no need to explain the bigger threat that would face all humans in the case of common use if the computers and/or the system had a flaw …Some may also question this technology whether it is necessary for human beings or not. The fact is, we have survived without it an dyes it does have appealing advantages that would make life easier but may not be worth risking the major threat we may face if this technology was to spread worldwide.To solve this issue, I would suggest that no one needs to take action at this moment as it is still in the process of developing. Its true potential and the possible advantages and disadvantages can only be proven once it is used.
