Andreesen lucked into being the first person to successfully create the world's most inevitable and obvious product. He did nothing but take a swing at the right time and get traction thanks to the taxpayer funded educational establishment he was in.
Following that luck he mismanaged the business to the point of total failure, slowing the development of the independent web and handing the reigns to Microsoft. An error we're only now truly emerging from thanks to the rise of mobile and the unmasking of Google for what it is.
In the interim he took the money he lucked into to write manifestos praising fascists as thought leaders and elevated people like Zuckerberg whose products have fueled genocide, the spreading of lies and insurrection.
Andreesen is a parasite who thinks the animal he's feeding from is dependent on him.
