Kevin Systrom (Instagram founder) worked at Twitter in the early days and he said that Jack was super smart and hard working which I doubt with all respect to the Twitter. He grandiosely failed at managing Vine which was supposed to be TikTok before TikTok. Vine could've been bigger money making machine that Twitter is or was. Also If I was Twitter CEO, I would've acquired popular blog platform Medium which was founded by Twitter co-founder and then I would build massive ad-network (Twitter, Vine and Medium) which could stand up against Facebook's and Google's ad business at least in the eyes of advertisers if not investors.

Also Zuckerberg wanted to acquire Twitter in the 2008 for $500m because in his paranoid head, he was scared that perhaps Twitter could overtake Facebook. Let me be clear, Zuckerberg is cutthroat competitor that doesn't care about anything except success. And looking at the Zuckerberg's track-record he won't let go this massive opportunity which is basically to kill off Twitter with Threads without much effort because Twitter is and was imploding for a very long time.

One side-note about Kevin Systrom; he said that back in the day when he co-founded Instagram, he didn't hear and know about AWS. So I must come to the conclusion in this ad-hoc way that not all successful founders know what they are doing and yea there is a lot of luck involved. And btw he is a Stanford graduate?! What is Stanford teaching these "kids"?
