Your brother's livelihood is not safe from AI, nor is any other livelihood. A small slice of lucky, smart, well-placed, protected individuals will benefit from AI, and I presume many unlucky people with substantial disabilities or living in poverty will benefit as well. Technology seems to continue the improve the outcomes at the very top and very bottom, while sacrificing the biggest group in the middle. Many HN Software Engineers here immensely benefitted from Big Tech over the past 15 years -- they were a part of that lucky privileged group winning 300k+ USD salaries plus equity for a long time. AI has completely disrupted this space and drastically decreased the value of their work, and it largely did this by stealing open source code for training data. These Software Engineers are right to feel upset and threatened and oppose these AI tools, since they are their replacement. I believe that is why you see so much AI hate in HN
