Yet Another Rant About Blockchains

I&#x27;d like to address this bit:<p>&gt; The classic rebuttal against blockchains and other distributed technologies goes something like this: there&#x27;s nothing a blockchain can do that a plain old SQL database can&#x27;t do cheaper and more efficiently. That&#x27;s true, but it&#x27;s also missing the point, and I&#x27;ll leave it at that.<p>That is definitely not missing the point when it is raised in response to things that are sold as &quot;OMG blockchain!&quot; but do not need (or often, even make use of) what makes blockchains unique. Which is, IMHO, at least 95% of the things that I come across marketed as involving blockchains.

One of the author&#x27;s points seems to be decentralized technologies tend to have large points of centralization, so why does it matter that they&#x27;re decentralized?<p>For me, the answer is the ability to opt out. When it comes to crypto currency specifically, it doesn&#x27;t matter to me if 99% of users store their money on coinbase, as long as I individually have the ability to remove myself from the system.<p>The point isn&#x27;t to force decentralization on everyone, it&#x27;s to provide an opt-out ability to those who want it.

This is why I am very hesitative to accept a job in the &quot;blockchain area&quot;, and I am still not convinced that I should.<p><i>Every single time</i> I asked the question &quot;how do you guys make your money?&quot; it has been evaded (&quot;we work in the finance area&quot;, thanks, that explains everything!) or has been paraphrased into &quot;is my job secure?&quot; which was then answered positively. I mean yes, my main motivation to ask is indeed about if my job is secure for at least a year -- in an area where people secure investor money by promising basically thin air, but I am also asking the question to gain an understanding of the company&#x27;s business culture. And I haven&#x27;t got the slightest idea of that after 7 interviews in the last 5 months.<p>I simply cannot wrap my head around this mass halucination. How are investors even agreeing with giving several million bucks to an enthusiastic young person with zero business planning? And zero ideas how will they repay the investment? The pitchers (future CEOs) are just like &quot;we are totally gonna revolutionize area X with blockchain!&quot; and then money starts rolling in.<p>I am sure I am over-simplifying but still, can somebody explain this process to me? I am still baffled to this day.

He quotes Scott Alexander on &quot;Moloch&quot; (an essay I haven&#x27;t read yet), &quot;In some competition optimizing for X, the opportunity arises to throw some other value under the bus for improved X. Those who take it prosper. Those who don’t take it die out.... The process continues until all other values that can be traded off have been – in other words, until human ingenuity cannot possibly figure out a way to make things any worse.&quot;<p>Is this not a fancy way of describing what&#x27;s usually called the Tragedy of the Commons?<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tragedy_of_the_commons" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Tragedy_of_the_commons</a>

Off topic but doing blogs on Notion seems like a really good idea. I like the format.

I&#x27;m likely guilty of being a naive technologist. I appreciate this different perspective.

Huh someone is typing in that post as I read it. Pretty cool, but confusing.
