Human are the smartest!
After the collapse of the tech industry, life became very hard. HTML CSS JS developer were found on the street searching for food and job, as the number of job decreased in the FANG, the number of people looking jobs in startup increased, causing even more chaos. The failed developers started selling their body part to survive.
Now are you scared. Don't be scared. Life is unpredictable, this can totally happen. So be a bit religious, go spend time with your kids and family. Don't think too much, after all, you can't avoid things that will happen. Maybe you can try creating a startup to help this hopeless developer connect with customers.
