Something you need to consider is the time differential between discovering something and getting it approved by the FDA. The FDA and medical regulations are notoriously slow, inefficient, and conservative. It's improved considerably over the last 50 years, but 6-7 years is still a tiny amount of time when it comes to medical research. It would be considered a quick approval to go from finishing research and getting it approved within 5-10 years. All those breakthroughs you read about 6-7 years ago are currently at varying stages of the clinical trial process, and many of them will likely see the light of day within the next 5-10 years.

​

Also, a well-known concept in economics is that it can take decades to go from discovering something and implementing it. There are several reasons for this, but in this case, the most important one is the need for complementary technology. Even if we could prove a gene had a certain effect and correct it with gene editing 30 years ago, it cost too much and was too inaccurate to be safely implemented. This is what changed over the past 10 years. We now have the technology to implement gene editing, reverse the epigenome, and kill senescent cells affordably and safely. In the case of gene editing, it only got here within the last 5 years. Within the next decade, we're going to see the floodgates open when it comes to medical innovation.

​

Edit: I forgot to mention that AI is another complementary technology that only got here recently. AI has increased research efficiency within biotech exponentially over the last few years. You only need to look at AlphaFold to see the effect it can have.
