Many things, my friend
The concept of borders
This situation is sure to go into recession mode soon. As most would agree, the spread of the epidemic is far worse in parts of Europe than in the Indian subcontinent, and border controls are far more porous in the former than in the latter. European governments, especially in Western Europe, will be forced to adopt stricter rules about who or what can cross international borders in the coming months or years.
This is the typical border in Western Europe
France-German border
Meanwhile on the Indian subcontinent
IMMIGRANTS:Countries such as the United States, the United Kingdom, France, or any of the countries that have suffered a serious blow may impose stricter visa rules on people coming from places they deem to be too dangerous for the public ****ing safety of their citizens.
This means that many people who wish to leave their countries now have no other option but to stay home.
People of credibility
An important fact is that in the current coronavirus crisis, WHO seems to be working less like WHO and more like some support base for China and the Chinese government, and a lot of the blame for this should be placed on the current WHO director general[1]
Perceptions of and support for China
For the coming years, China and the Chinese ****production party will be seen as an increasingly negative issue by other countries and their people.
China's promotion of bear bile as a treatment for coronavirus alarms wildlife advocates
Obviously, there will be many countries that will have a very pessimistic view of China. I wouldn't be surprised if a few countries take tough measures against China, from banning their own people from visiting China to preventing their own people from establishing business ties with China.
Visual communication minus proximity
I'd also like to say that the ongoing crisis may soon bring about a time when:Unless it is extremely necessary, all important meetings, conferences, and seminars will be held only by [2][3] videoconferencing.
The concept of videoconferencing is not new, it has been around for about 20 years or so, but not everyone likes to use it or can afford it. This is expected to change in the coming months or years with even the general public in mind.
It's important to note that video calls on Skype or Whatsapp are not what I'm talking about. I'm talking about Cisco-style stuff. When was the last time you heard your average Joe call his friend by something Cisco?
Homeschooling and homeschooling methods
It's likely that students will be forced to homeschool for years to come.
I don't know if you know this, but when I was in school, there was an excerpt from a book by Issac Asimov about the future "e-teacher-computer," which, as the name implies, would have the sole job of teaching and nothing else. Of course, this story illustrates that computers are not infallible, but teachers' computers don't need to be. We live in an age of online courses and online journals, and these things may well become the new way to learn.
When it comes to young children, parents will have to become the new teachers.
CBRN's defense will be absolutely serious
Most of the world thinks that nuclear weapons are the biggest threat, ultimately forgetting that an outbreak of a pandemic could cause a lot more trouble than nuclear weapons.
Most countries with militaries tend to have a large portion (if not every country) that specializes in CBRN defense[4] (CBRN = Chemical, Biological, Radiological Nuclear). However, some countries tend to have a department, and sometimes an entire branch dedicated to CBRN defense.
For example, the United States has a specialized "Chemical Corps", as do Russia and the United Kingdom. These organizations are not the regular soldiers you train in the CBRN, their only mission is CBRN defense.
I wouldn't be surprised if some country builds its own CBRN defense force with a lot of money.
Self-reliant nation
Special thanks to Nivedita Bhattacharya for giving this idea in the comments.
Countries that previously had to continue to struggle with medical equipment purchased from countries that have long produced it may now have to start relying on themselves. Most of these countries will serve themselves before they serve other countries, so time is when things that can be done on their own will have to start being done on their own.
For example, two countries, India and Bangladesh, have recently made test kits that are not only reliable but also cheap. Similarly, the Mahindra Group[5], an Indian company known for its cars, makes a reliable, affordable ventilator
This habit is likely to expand to many countries in the years to come, and not just for medical equipment, something that many countries desperately need.
