Apart from the obvious implications (physical/psychological/economic) of COVID-19 outbreak, here are some ways it could change the world:

New architectural thought process containing wider spaces for corridors, larger offices, broader workspaces encouraging 6 ft gap between people. Change in fashion/design of clothing that would discourage inhaling of pollutants and encourage gap between people. Sensors mounted on people (say cap of the person or a jacket) that would alert when other people are too close to you? Too extreme, I know. But foolproof. Decrease in world pollution and CO2 now and sudden rebound (more than the normal levels) in transport once COVID-19 is brought under control causing new environment patterns? Takeover of wildlife (animals/plants) amidst absence of personnel and tourists in forests and parks. New type of seating arrangement in theatres, passenger planes and cinemas which allows for only 2 seats (for family to sit together) to be close to each other and then a gap between every two seats. Massive boost to consumer and "essentials" industry as people buy more and stock food and other essentials. This in turn could mean higher pay in these industries as the scale and volume leads to more profits (already food processors and Walmart in Canada has increased pay). Basically, most sectors would grow weak where job losses would take place in this short duration while COVID-19 outbreak lasts, while these few industries experience growth. Boost to Netflix, online gaming and other streaming services as other options such as outdoor games, concerts and cinemas remain suspended. Boost to Virtual Conferencing companies like Zoom & Webex and in the long term, a decrease in travel for business needs as people become more used to and familiar with these virtual options. Reduction in war activities as mobility of soldiers decreases and the countries deploy these resources in their own cities to maintain curfews. More funding for research related to illnesses and viruses. On the flip slide, spending on climate change may decrease, as this would be seen as a far-off threat comparatively. Millennials who had taken cooked food for granted thanks to services like Swiggy/Zomato/Uber Eats would now need to learn the importance of essential skills like cooking. No maid visiting their homes would mean, they would also need to learn to do their dishes, wash their clothes and clean their homes (applicable to my home country - India) It would take a while for family members to feel comfortable living and working in different spaces as now they are not able to support each other due to travel restrictions amidst COVID-19 outbreak. Rise in e-commerce. Brick & mortar shops all the more closer to permanent closure. Proving/disproving that online education/work from home is possible and effective. Make us understand why our grandparents/grandparents' parents generation had a tendency to hoard food. Because you never know when it would be difficult to get hold of groceries again. Global Recession/Loss of Jobs which could lead to increase in crime rates. Intrusion of work into your personal space and personal things interrupting work. Tourism/Travel - a standstill. A rise in MOOC certifications. Fall in real estate prices as some companies figure out that loss in productivity, if any, by working from home, is more than compensated by saving on office rent.
