Nothing is used everywhere. And the bigger the system, the more disparate the sub-systems will be. And that is guaranteed by economics, not technology.

And Oracle had support for Object Oriented Databases in the 90s (if you will the precursor to NoSQL) and yet it was used very little.

If you check it out you will find the author (at least the first one) is specializing in providing legal support for companies that use blockchain. So certainly not an unbiased view of the potential. To be fair pretty much any technology that reaches even a small audience is going to attract cheerleaders that seek to promote the technology while basing their own financial future on the success of what they are promoting.
And there could be success stories. But there will be failures as well. Guaranteed since some of those have already happened.

How about atoms? I believe they are even used in the most distant suns and at the far edges of the Universe.

And yet, where is there an unbiased view of anything? Many people like chocolate and yet other fools do not. And people who sell chocolate like it even if they don't eat it themselves, all because they are trying to make money. I have yet to find the human who has an unbiased view of anything. Whether they know it or not. But, that's just my biased opinion. 
I get your points though. I know there will be vast challenges for blockchain tech but that is what struck me the most -- the huge corps who are getting behind it. I'm not really _for_ blockchain since there are some inherent dangers in it. I just think the technology behind it (merkle trees) is interesting and since I don't like large systems I find it to be interesting that so many large companies are backing it so strongly already.

You get an unbiased view when people share theoretical implications and practical applications.
You get a biased view when people are sharing an emotional stance about something.
Some people employ both and expect you to discern between the two.
Some people only employ the latter.

Large companies use a lot of things. And they try a lot of things because they have the money to throw away. That doesn't mean anything. Even more so because marketers like to promote exactly that usage.

What statistics? How many fortune 500 companies have invested more than 50 percent of their total IT dollars in it? How does the actual investment of those same companies over the past 20 years in other technologies compare?

Jokes and interesting facts aside, we shouldn't gloss over the fact that it almost doesn't solve anything.
Pragmatically speaking, it's just a persistent data-store.
Noteworthy characteristics are:
- it's highly distributed
- data authenticity is expected to be safe, as long as no bad actor owns ~40% of the distributed parts
- it's not high volume
- it's not high capacity
As a result, it's an expert-system than only works when you have a lot of users and can't trust anyone, and these need to be your primary concerns.
The only profitable market that has these requirements is the illicit drug trade. And mayhaps cyber warfare, in 2 or 3 years time.
In all other circumstances where you could apply a distributed design, you're better of with a trust-based system (= certificates) and support for high volume and capacity.
This is like data-mining all over again.
People who don't understand profit and the practical application of software are writing books and giving seminaries about things that no-one will pay for.
Marketing to idiots doesn't count, because that's short-term only. Idiots don't have a long attention span.
To be honest, It just annoys me that enterprise is faking interest again and fanning the flames.
Intel and IBM have a track record of publicly investing during hype cycles and then abandoning those projects when their stakeholders stop noticing.
I'm still pissed-off about Edison.

Great points all around.
It is worth noting that it has proven to be useful for inventory tracking and it's nature lends itself to cross-company resource tracking, making the possibilities for ERP solutions interesting.

Yes, it can be applied for B2B inventory tracking, but you'd need a trustworthy intermediary to provide the infrastructure / inventory service, and you'll probably pay a hefty premium to integrate it with your ERP out-of-the-box.
Alternatively, maintaining a plain-old REST point and a SignalR hub is cheaper and aligns better with a healthy software stack.
And, to be cautious, you'd probably want trusted interactions when doing any B2B related activity.
Companies tend to sue each other a lot when something goes wrong.

Not denying any of that. Just emphasizing that while it's largely snake oil, there are practical concerns that it can address which are largely being lost in the current buzzword mess.

Well, the hype cycle is already going down, so maybe in a year or so we'll have sensible applications.

I know. That was a crazy situation. I actually won an Edison in a contest and when I got it I thought it was too complicated (for what it was). What I mean is that if I wanted that level of a thing -- running Linux -- then I'd just go with the RPi. and if I didn't want something running Linux then I'd just go with a basic Arduino. It was as if they created this thing without looking around at all.
It was crazy they just killed it like that though. People were just starting to use it a bit.

I wanted the prototype.
The prototype Edison was packaged on an SD-card format with WiFi capabilities.
Power draw was promised to be compatible with standard SD-card max draw.
I know at least 1 of those got build.

It simply means that there are code examples to follow.
Do you know about the tech behind blockchain? Merkle trees? Quite interesting. How might they be used. That's the interesting part. And seeing how the BC is implemented on top of that. Quite interesting.

I agree, it is quite interesting. If it is to be a tech juggernaut the world may need a couple dozen reactors and some tons of uranium. I hear implementation gobbles electricity like Joey Chestnut eats hot dogs.

The only "demonstrated" application has been cryptocurrencies.
It has not been shown to be cost-effective for much else; particularly "private" use.
Only the "vendors" seem to have all the answers ... Where else are you going to get all those "nodes" for your computations?
