To add to the “the real issue is…” pile:

Most orgs collect the data that is easy to collect, and they are extremely lucky if that happens to be the data that enables the insights they desire. When the data they really need looks too hard to get, the org tries to compensate by collecting more of the easy stuff, and hoping that if blood can’t be squeezed out of a stone, maybe it can be squeezed out of 100bn stones.

Big Data was whatever someone couldn't handle in a spreadsheet or on their laptop using R. This paper is 8 years old and it was somewhat obvious then. Scalability! But at what COST? https://www.usenix.org/system/files/conference/hotos15/hotos... A big single machine can handle 98% of peoples data reduction needs. This has always been true. Just because your laptop only has 16GB doesn't mean you need a Hadoop (or Spar…

You can do a petabytes of analysis with regular old BigQuery just as easily as you can analyze megabytes of data. This solves the scalability issue for a lot of companies, IMHO.

I agree with many of the points here. My cheap no-name old laptop SSD writes with 170MB/s. A customer has a name, address, email and order. Let's say 200 bytes for each. That means I can write 844000 new customers per second, far outside my personal marketing reach. My disk is 240GB, which means I can store data for 1.2 billion customers. It'll take a while until I become that successful.

It never sat well with me that none of the production services could leverage my local computation and storage power. I don't need to store my contacts on a remote server that could index my contacts when mixed with every other contact in a single table. That’s a blatantly oversimplified example but you get the gist.

MotherDuck has been making the rounds with a big funding announcement [1], and a lot of posts like this one. As a life-long data industry person, I agree with nearly all of what Jordan and Ryan are saying. It all tracks with my personal experience on both the customer and vendor side of "Big Data". That being said, what's the product? The website says "Commercializing DuckDB", but that doesn't give much of an idea of…

> DuckDB is already super easy to use out of the box, so what's their value-add?

I think this is analytics equivalent of edge computing. Instead of one big-cluster cruching numbers.

1. User requests bunch of analytics

2. Server assembles a duckdb file

3. Sends this down to users laptop

4. User runs local queries on the duckfile

5. Go to step 1 for more analytics

"For more than a decade now, the fact that people have a hard time gaining actionable insights from their data has been blamed on its size." The real issue is that business people usually ignore what the data says. Wading through data takes a huge amount of thought, which is in short supply.

Agree with some of what you've said, but disagree with a lot:

> Most corporate decision making is highly political, the needs of/whats best for the business is just one parameter in a complex equation.

100% Individual humans are emotional creatures with their own wants and needs, and it's important to understand how organizational incentives drive decision making.

> Data Scientists are commonly disregarded by VPs in large corporations, despite the claims about being "data driven".

This has not been my experience, though. The more common thing I've seen is that, sometimes data is boring and doesn't really show much actionable insight, but as everyone wants to justify their job, I've seen data scientists come up with really questionable conclusions that fell apart on further inspection (call it "p-hacking the enterprise").

Plus, a lot of this data in these data wearhouses is messy. Often times data scientists are siloed at the end of the process, but then you get "garbage in/garbage out" results, where there is some bug in data tracking that isn't understood until it's too late. Much better in my opinion to have data engineers and data scientists work much more closely with product engineering teams up front so they can help ensure the data they collect is accurate.

> I used to joke that Data Scientists exist not to uncover insights or provide analysis, but merely to provide factoids that confirm senior management's prior beliefs. So, a synonym for 'consultant?' :)

My experience with consultants normally ended up with them asking why they are there and what report should they present to upper management. I've always used them as "independent 3rd parties" who were listened to.

"A prophet is not welcome in his hometown"

This has been going on for mellennia, unfortunately.

I find a lot of organizations don't have the discipline to harness whatever power their data may have. Sure collect everything, but god forbid you have any sort of data governance, or spend a single resource minute of time manually tagging or organizing or validating it. Then they try to make shitty ML models or products out of it, but don't care if the models actually work or not, just that they have AI now. Then a year later when the model has provided no value they are like, oh well big data is worthless I guess.

"customer obsession" was always at the mercy of the real obsession: "making money hand over fist". The former will ALWAYS lose out to the latter given enough cycles.

Yeah, "customer obsession" really just means "market share / growth obsession" which is a means to (eventually) making monopoly profits. Which Amazon seems to have achieved.

All the amazon corporate values are derived from making profit. Two-pizza teams? More like "three slices isn't frugal", one or two should be enough for you.

I used to joke that Data Scientists exist not to uncover insights or provide analysis, but merely to provide factoids that confirm senior management's prior beliefs. I did several experiments, and noticed that whenever I produced analysis that was in line with what management expected - my analysis was praised and widely disseminated. Nobody would even question data completeness, quality, whatever. They would pick so…

Oh the experiment didn't go as expected? Rerun 5 more times with minor tweaks. It definitely not p-hacking ;).

I’ve been there, we wanted to release a feature, it kept coming back with issues that made it perform much worse than control, after 5 or so iterations with bug fixes it came back positive.

It took a lot of analysis and time to clarify to higher ups that we weren’t just P-hacking , but at least they were concerned about that.
