It will be very, very tempting for companies to let people go when LLMs can do everything that they envision the people doing. It is very hard to resist the cost savings that LLMs have over people. People who get sick, get married, go on vacation, have children, and sometimes just need a break, so they don't come in. LLMs always come in. LLMs always work.
Many executives see LLMs as the ideal replacement for humans in information roles. That is clearly batshit insane but the numbers really lean towards this if you're someone who is distant from people who work for you.
Companies would do well not to forget that companies are of people, by people, and for people. they exist solely to provide products or services to people, be it actual individuals or companies which are made up of people.
If companies ditch too many people in favor of automation, they'll find fewer customers for their goods. because people won't be able to afford them, or will have no need for them. it's not like there's some huge need for LLM trainers to take up the unemployment slack. There is no replacement industry this time.
