Why do we think this is? Might it be because big companies would actually have to face consequences when big, dumb risks fail?
> research organizations and academia will take risks without investing
Not sure where you get this idea
> branches of government and political entities (in the U.S.) are famously bad at both (ex: healthcare.gov)
I'm not sure if healthcare.gov is a great example, since IT for the site was almost entirely run by private contractors. Before corporate lobbying was able to handcuff essentially any public innovation effort, the government routinely funded massively successful innovation projects (civilian aviation, the internet, microchips, satellites, AI, barcodes, touch screens - including the company bought by apple, nearly all devices and drugs/vaccines used in modern medicine, list could go on forever basically).
> Blame anticompetitive behavior all you want
I will, since once again, we've seen all of the alternatives be successful without nearly as many downsides.
> the current internet model favors VCs because R+D is cheap and quick
I'm not convinced. Largely the current model wins because it sidesteps regulations and gets away with anticompetitive, antisocial behavior and risky financialization under the guise of innovation. If it was true innovation, the world wouldn't be becoming a worse place every day that SV was essentially handed the keys. Our kids wouldn't be more depressed, climate change would be addressed, public health crises would be solved. What we have is a bunch of people scrambling trying to impress upon people that they have all the answers, when they do not.
I'm also not convinced that the answer to everything lies in the internet. Nearly all of our savings has gone to funding companies that do a thing that existed, but on the internet, rather than funding real innovation.
