Putting another $10m to follow it would be chasing good money after bad, and fall into the sunk cost fallacy.

We live in an attention economy. If you read a story, or watch a video, it doesn't matter if you agree or disagree with the content; you're still traffic.

Just viewing content on most of the internet boosts it's signal, and creates value for someone; much less engaging further by commenting, up/down voting, or sharing it. It's a pretty ugly system.

Getting a dollar from a million people is a different thing to getting a million dollars from one person.

It seems cheap relative to pretty much anything these days. People pay that much for rare cars, a rich person could snap their fingers and make it happen. I hate to tell people how to spend their money but I wish someone pitched it as an experiment to Elon Musk or Bezos. Just like you said - put it in space, switch it on. Either it works or it doesn't, should be obvious straight away, no?

Make it happen!
