That’s probably not “Rails create” but very well could be “Here’s how we deploy on Rails and why we made these choices.”
Or in banking not “Here’s what net interest is” but “Let’s talk about funding sources available to banks and the relative costs and limitations of them.”
Hmm *writes note to self.*
Interestingly I think a lot of people worry that they have to write something which would flawlessly educate e.g. a 20 year industry vet to justify hitting publish.
1) There are a lot of professionally relevant people who aren’t.
2) Experts enjoy tight, well-executed material!
The modal coffee conversation with people at the top of the field is not about the absolute edge of the field, it’s about the quotidian work that supports the ability to work at the edge!
(And a lot of experts really, really enjoy that quotidian stuff either because they miss it or because they’re experts *because* they love all these messy details and they found a job that lets them geek out about the thing they love.)

"What would the grown-up financial economy do if it lost $70 million?"
It is difficult to answer this question because it should be nearly impossible to lose it to anonymous counterparties. Everybody you're connected to has a name, an address, a phone number, etc.
I remain surprised by how much better my life got by the really simple expedient of making batteries a pervasively available utility, even though I'm not often away from an electrical outlet during coronavirus compared to more typical life pattern.
The dominant use case for me is "Drop daughter off at school, would really like to go to a cafe and enjoy breakfast but cannot justify it if cell phone is off, see I only have 4% and think about going home... pop into konbini, rent battery for ~$3, get to enjoy coffee."
And it's such a good business for all parties that the local konbini moved the station, which both handles payments (with the app on your phone) and fulfilment of the battery, away from the register because frequent transactions were blocking foot traffic to the checkout.
Also there is culturally more willingness to grind a bit on marketing and sales where a lot of us back in the day reaaaaaally wanted to make a software vending machines, put it on Internet, and never have to talk to anybody.
An interesting thing from the crystal ball: a lot of what has historically made this form of software entrepreneurship attractive is that most founders of it live somewhere where they are the best game in town for a software dev.
One of many articulations of the thought, though I wouldn't use the word "bubble" these days; in core tech (ex-crypto) degree of investment seems extremely rationale to me.
Software takes money to build, and that money has historically been raised by professional money people.
Software makes software people money.
It is very not obvious that professional money people add value other than the money, and to the extent they don't, why have them.
A very useful thing to know, if you sell things that could be used by a company that would have need for a hundred pretty nice workstation GPUs, is how this calculation gets made in practice:
Technologist: Residual value is $4k contingent on sale.
Manager: Do we have a buyer on the approved vendor list who will do The Usual with less than one phone call required?
Technologist: No.
Manager: Trash them.
Technologist: Why?!?
Manager: We’d only spend hundreds of dollars of staff time, I.e. yours, if this was a simple matter of boxing them up and giving them to vendor. That might or might not be worth it given typical ROI on your time given current workload/priorities. However.
(Not wholly descriptive of things I’ve seen in my career but really important to understand broad strokes of how large software-oriented orgs operate compared to small shops and large non-software orgs.)
(And while there are lots of differences between and within companies it is, unsurprisingly, trivially true that e.g. eng team randomly picked at Google is more similar to one at Amazon than a randomly selected writer of code at Washington University or the IRS.)
