I don't really like Micah much to begin with but his take on the web thing wow yikes. also Steve I'm very disappointed in you man. you're basically throwing your hands up and saying well to hell with it let the bad guys win. you're basically saying that we shouldn't even try. the internet is not free it's cost is our sovereignty our freedom and our future. if it continues the direction it's going it's going to do more damage to humanity than it will ever help. This is the worst take ever.

I really love listening to your podcasts and I love how enthusiastic Steve gets over some news and his voice is really cute 😍 I just wish you guys would give a short definitions of some acronyms or techniques you're talking about, so I won't need to pause and Google, specially when the room is dark 😀

Epidemiological experts say this is just another flu, do not let these political hacks kill you as they ignore warnings mitigation efforts prolong the virus? That is why the bat lady from China on day one said try malaria drugs, they open a channel into the virus so zinc or something else can bind instead of oxygen robbing iron stolen from your body? Would you help politicians round up people to put them in killing machines they could blame on a virus? I don't think so. You delay respi
