If you want to hear two guys rattle off ‘news’ about companies nobody cares about, this is your pod. Some company acquired another company - snooze. Another company raised some money - zzzzz. The hosts even sound half asleep, how is anyone else supposed to find this drivel interesting.
The insight and analysis from Matt and Nic is unmatched. I look forward to this recap every week. An absolute must listen. (Praying some terrorist turkey doesn’t take Matt out.)
The way you’ve flipped the pancake on the bad actors in your industry and inability to call out the grift going on by the White House is hugely disappointing. CZ gets pardoned and you call this “controversial”?? Your listeners have longer memories.
bleh
Nic’s amoral embrace of all things AI strikes me as particularly soulless. And shameless. Very useful to him no doubt but on the human level, appalling. I am disgusted.
