Today, when medical technology development is over-hyped, people should not blindly believe in current or future healthcare technologies. With an objective, rational and optimistic attitude, let us look at the medical technologies that are over-hyped and bear in mind the realities of these technologies in the process of recovery.

You must have heard such a proverb: Pessimists will say that half of the glass is empty, and optimists will say that this glass is half full, and cynics will ask, who is drinking that half? And I am a full-fledged optimist, especially in the development of medicine and health care.

But my optimism comes from the facts and objective judgments on the latest developments in the medical field. The attitude of seeking truth from facts is very important, because the media often exaggerate outstanding medical discoveries, creative medical solutions or short-lived experiments to gain the attention of the world. Although this does not improve the viability and sustainability of these medical technologies, the relevant reports have indeed attracted people's attention.

Let's take a look at Theranos and its infamous founder Elizabeth Holmes. After blindly expecting ten years, the Wall Street Journal finally began to seriously question the blood test of Theranos. Now, we have to wait for Theranos to announce more technical details. Look at optogenetics again! The technique of using light to control cell behavior in living tissue is still a blank check. Look at the iKnife that claims to detect cancerous tissue during surgery! It almost disappeared completely.

If a medical discovery is too good, then we should be extremely cautious in seeking clear evidence before disseminating relevant information. False hopes are very dangerous.

Therefore, we need to put aside the excitement and optimism, conduct in-depth testing of revolutionary medical technology and prove its rationality with evidence. Excessive speculation can only lead to development failure or an investment bubble. We can avoid this by pointing out its shortcomings, and we hope that the researchers will achieve amazing success. Next, the author has counted 12 medical techniques that have been over-hyped for you.

1) 3D printing drugs

On a very boring Wednesday afternoon, my wife asked you to go to the corner of the pharmacy to buy medicine. You told the pharmacist the name of the wife, and it was not long before the pharmacy printed a personalized tablet for her. This capsule is made according to her requirements and molecular background, according to the dose prescribed by the doctor. Sounds great, right? Unfortunately, we are still unable to achieve this vision...

In 2015, the US FDA approved the first printing drug, Spritam, which is an epileptic drug that dissolves quickly. I also envisioned a small pharmaceutical company that would make drug metabolism faster with new solutions and use this manufacturing method to simplify the sales process. I once thought that the redesign of the entire pharmaceutical supply chain could be completed in a few years or even months.

However, I am too optimistic. The current drug production process is relatively slow. And pharmaceutical companies are reluctant to replace new drug production technologies that they have used for decades.

2) Diabetes-specific digital contact lenses

In 2014, Google submitted a patent for multi-sensor digital contact lenses to the US Patent and Trademark Office, which detects blinking movements and flips pages for e-books in a blink of an eye. Later, people proposed more creative uses of contact lenses, such as measuring blood sugar through tears.

In 2014, Google announced that, according to its most optimistic estimates, digital contact lenses could be launched within five years, and related trials would be conducted in advance. But then Google repeatedly postponed the press conference, flashing its words on the development of contact lenses. In the official announcement, Google even said that scientists have done a lot of research on the ability of certain body fluids to reflect blood sugar levels, but because of the difficulty in collecting and researching tears, measuring blood sugar using tears is somewhat whimsical.
