500,000,000*80=40,000,000,000 40,000,000,000/650,000,000,000=0.06

If I understood you correctly and my math is correct, your suggestions only cover 6% of 650 billion, the news is suggesting AI companies need more than 10x more. So either it's 5 billion people paying 60-80, or 500 million people paying 600-800/month, or something in between + a little extra.
