Over these past four years, pretty concrete things happened: tons of companies started using AI to automate repetitive tasks, but it also opened up a huge gap between those who learned to use it as a tool and those who got left behind. The real shift wasn't AI itself, but that people had to relearn how to work almost overnight - some adapted quickly, others not so much.
What nobody talks about is that the best approach is to stop seeing it as a replacement and start using it as a first draft: I generated summaries of long articles, but I always checked everything because at first it made stupid mistakes. Whoever figured this out early ended up being more productive than someone who expected the machine to do everything perfectly. In society there was panic about job losses, but the reality is more mundane: some jobs changed in nature, others disappeared, and new roles emerged. Nothing spectacular, but enough that you have to rethink what to do every five years.
