Three years ago, AI was just a buzzword. Now it is everywhere — in emails, in meetings, in code, in customer support. The world of work has changed, and many people are still trying to understand what it means for their careers.

Some companies have introduced AI tools to make work faster. Marketing teams have started using ChatGPT to write copy in minutes. Designers have tried Midjourney for first drafts. Developers have used Copilot to write code twice as fast. At the same time, big tech companies have laid off thousands of workers since 2023 — and many of those people now compete with AI for the same jobs.

My friend Anton is a junior designer. Last year, his manager asked him to learn five new AI tools in two weeks. He felt stressed at first, but he has become much faster since then. \"I have not lost my job to AI,\" he says, \"but my job has completely changed.\"

Not everyone is happy. Some workers say AI has made their jobs harder, not easier. Last month, I read a story about a translator who lost half of her clients in just one year. She has tried to find new work, but most companies now ask for \"AI-assisted translation\" only.

\n\nQuestions on the text:\n1. What has changed for marketing teams, designers, and developers since AI tools became popular?\n2. Why did Anton feel stressed at first, and how has his job changed?\n3. Find one Past Simple sentence and one Present Perfect sentence — explain why each tense is used.\n4. Have you used AI at work? Has it helped you or made things harder?","order":7,"title":"AI at work: friend or enemy?"},{"id":"b8","type":"open_question","content":"

Some people say AI has helped us — saved time, made work easier, opened new opportunities. Others say AI has made things worse — students cheat, workers lose jobs, fake content is everywhere.
