I learned vi (precursor of vim) in the 1980s and the commands became second nature to me. However, as window-based systems and applications became the norm, I found it difficult to switch between vim and Windows or Mac applications, including the web. A good example of my problem involves the use of the escape key in vim to switch out of text entry mode, but many other apps use escape to cancel an action. I got tired of typing a paragraph, hitting escape, and then having to retype the paragraph because I had cancelled my input.
Nevertheless, it's great to have an editor I can easily invoke from the Linux command-line, so I still use vim for that. However, I will consider moving to nano for that purpose. At my age, I may never know it as well as the vi/vim I learned in my younger days, but it should still be useful.
But that's for small editing tasks. For coding I use VSCode or a JetBrains product.
Farmed animals like minks and racoon dogs were kept in cramped breeding conditions. Rhinopholous bats infected with sarbecoviruses are also present in Hubei. Those bats probably roosted above the animal pens and shit down on the animals below for years. The animals would periodically become infected. Eventually through mutation or recombination a strain became epidemic in the animals and evolved to be successful in a very closely related ACE2 receptor to humans.
Then you had a large bioreactor which spread the virus doing "gain of function". Eventually it swapped backwards and forward from humans to those animals until it acquired the ability to spread epidemically in humans in late 2019.
That process absolutely could have evolved a furin cleavage site, or it may have simply been present in the bat version of the virus (like the RacCS203 sample from Thai bats). Recombination with human HCoVs may have also happened in this process where the intermediate animal coronavirus infected a worker who also had a cold.
When you read last year about the Danish mink farms with millions of mink being infected with SARS-CoV-2 you should realize that is a much better bioreactor to do natural "gain of function" experiments in than any BSL lab in the world has. Something like that, with a similar species, is likely how the virus hopped from bats to humans.
This actually better explains all of the suspect features of SARS-CoV-2 than a BSL program does.
For me, it is that I don't like all my purchases to be tracked in one giant database.
If you still use cash, what are your reasons?
