All great points! I listened to the podcast episode first

since my colleagues were all buzzing about it today lol. Then I pulled out this YouTube video, what caught my biggest attention in the video was the chart showing OpenAI's market shares had fallen so drastically in a short two years.... 

投資，在我看來，big picture 比narrowing to fundamental and technical analysis 更重要。OpenAI 現在的“布局”值得深思。謝謝你的分享！
