Study Notes

The Potential of Genetic Engineering with CRISPR

Humans have been engineering life for thousands of years through selective breeding, but it wasn't until the discovery of DNA that people began to tinker with it.
In the 1960s, scientists bombarded plants with radiation to cause random mutations in the genetic code, and in the 70s, scientists inserted DNA snippets into bacteria, plants, and animals for research, medicine, agriculture, and for fun.
Genetic engineering became commercial in the 80s, with the first patent given for a microbe engineered to absorb oil, and today, we produce many chemicals by means of engineered life.
The first genetically modified food went on sale in 1994, but GM food and the controversy surrounding them deserve a video of their own.
Gene editing was extremely expensive, complicated, and took a long time to do, but this has now changed with a revolutionary new technology now entering the stage—CRISPR.
Overnight, the costs of engineering have shrunk by 99%, and it offers the ability to edit live cells, switch genes on and off, and target and study particular DNA sequences.
Medical applications of CRISPR include cutting the HIV virus out of living cells, defeating cancer, and curing genetic diseases.
CRISPR could also be used for the creation of modified humans, starting with eliminating deadly genetic diseases, but eventually leading to a slippery slope of modifying vanity traits and enhancing intelligence.
Engineered humans might be better equipped to cope with high-energy food, eliminating many diseases of civilization like obesity, and might become immune to most diseases that haunt us today.
Challenges include technological and ethical issues, such as the fear of creating a world in which we will reject non-perfect humans and pre-select features and qualities based on our idea of what's healthy.
Wrong edits still happen as well as unknown errors that can occur anywhere in the DNA and might go unnoticed, and working on accuracy and monitoring methods is a major concern as the first human trials begin.
Scenarios like North Korea engineering an army of modified super soldiers are far off into the future, if they ever become possible at all, but the basic proof of concept for genetic engineering like this already exists today, and banning human genetic engineering would only lead to the science wandering off to a place with jurisdiction and rules that we are uncomfortable with.The Future of Genetic Engineering: Opportunities and Challenges
Genetic engineering has the potential to cure diseases and extend human life expectancy by centuries.
CRISPR-Cas9 is a powerful tool for editing genes, allowing scientists to modify DNA with precision and ease.
The technology is still in its early stages and needs to be guided by caution, reason, oversight, and transparency to avoid unintended consequences.
Most people have something wrong with them, and genetic engineering could help correct genetic defects and prevent genetic diseases.
The future of genetic engineering raises ethical questions about the limits of human intervention in nature and the potential for creating new forms of inequality.
Genetic engineering could lead to a new era of human evolution, where we can optimize our genetic traits and capabilities.
The technology also has the potential to create new forms of life and solve environmental problems, such as climate change and pollution.
The future of genetic engineering is full of opportunities and challenges, and it requires a balanced approach that takes into account scientific, ethical, social, and political considerations.
The technology is not without risks, and it requires careful assessment and regulation to ensure its safety and effectiveness.
The public needs to be informed and engaged in the debate about the future of genetic engineering, and their voices need to be heard in the decision-making process.
The future is approaching, and genetic engineering is becoming a reality that we cannot ignore or dismiss.
Further research and development in genetic engineering will shape the future of humanity and the planet, and it is up to us to ensure that we use this technology for the greater good.
