Prove me wrong: It’d be a huge mistake not to hold stocks for the long term because of AI

Assumptions:

• Companies can save exponentially more money with AI.
• For example, as a company, you used to have to pay $85/hr and a total of 10 hours ($850 total) to write a good blog post for marketing. With LLMs (large language models), you can generate an article and ask your writer to spend one hour editing it. The cost to produce a similar quality of a blog post went from $850 to $85 and the speed to produce it went from 2 days to 1 hour.
• Soon, many workers will be exponentially more productive.
• Things that used to cost a lot of money to produce will be cheap.
• We're starting to get generative AI in video games, movies, music, programming, etc. as well.
• Like the iPhone which made many workers significantly more efficient and opened entirely new industries, AI can and will likely do the same.
• Thus, corporations and stocks will benefit.
• There will obviously be big losers and big winners but as a whole, I expect S&P 500 to continue to marge towards greater profitability and a bigger total market cap.
