> "The principle of a cross-functional team is widely explained and described."

You are completely side-stepping the entire point and it's extremely disingenuous. You're acting like because the specific words in a Scrum principle says "cross-functional team" that it must mean everyone who uses scrum practices it in the most charitable, idealized way.

Instead, in real companies, terms like cross-functional team, regardless of any dictionary definition or intention in theoretical Scrum, are completely subverted for convenience of managers and business people. In particular, it's taken to mean that if a team needs more expertise in a skill area, it's fine to require training or expect self-learning in that area from existing staff, regardless of how wildly inappropriate it would be given their skill set. And because Scrum doesn't do anything about this, other than to vaguely encourage "cross-functionality", the problem shows up all the time in companies that use Scrum and is often amplified by it, with middle managers pushing back that e.g. my ML team ought to be trained in Javascript so we are "cross-functional" to write frontend GUI stuff.

When it comes to people with marketing skills, finance skills, etc., then of course they see them as separate domain specializations worthy of new headcount to grow the team's skills. But they lump all of software and information technology into a single huge bucket.

> "The companies I work for are able to understand that."

Your experience has been fleetingly uncommon then, to such a degree that it does not generalize to common or average situations, and therefore we ought to discount your experience as too much of an outlier from most of the industry.

Since you boasted about looking on job search engines for these crazy pan-everything job ads, yet you clearly did not actually look for them, let me do it for you and definitively prove you very, very wrong on it.

I searched for results containing both 'TensorFlow' and 'Scrum' on Indeed, sorted by newest, and just walked down the list of results.

< https://www.indeed.com/jobs?as_and=tensorflow%20scrum&as_phr... >

Here are some specific ads:

- < https://www.indeed.com/cmp/Thor-Incorporated/jobs/Big-Data-2... >
This one contains desired skills directly managing scrum teams, IoT expertise, tons of BI database systems, tons of machine learning frameworks, among much else.

- < https://www.indeed.com/viewjob?jk=a6693cf7a3422b247&from=ser... >
(This one is for a full-stack web developer that also needs experience in machine learning frameworks, cloud-based devops tools, "LEAN and Agile/Scrum", and about a dozen specific frameworks.

- < https://www.indeed.com/viewjob?jk=abe4938edc06babe&from=serp... >
(This one specifically names Agile, Scrum, JIRA, and Trello, amongst also listing specific deep learning frameworks, Node.js, Flask, and .NET, familiarity with healthcare data, 5+ years of ETL experience, and demonstrated front-end experience.)

- < https://www.indeed.com/viewjob?jk=c231123cf951f128&from=serp... >
(This one lists half a dozen databases, half a dozen cloud frameworks, Spark, Storm, BigQuery, Theanos, Tensorflow, Keras, Python, R, Scala, C++, Java, Ruby, Angular, React and then finally lists as the final item, "Drive agile software development practices (Scrum, Kanban, XP, test-driven development, DevOps)")

- < https://www.indeed.com/viewjob?jk=4f7f9564892a1c9a&from=serp... >
(This one lists front-end, Javascript, and Angular experience for a front-end role, specifically says, "Experience with an Agile development / SCRUM approach", and then also says "Experience working in a cloud based environment, such as the Google Cloud Platform (GCP), or the Amazon Cloud and using languages such as Jupyter and TensorFlow", which indicates a bad mistake (calling Jupyter and TensorFlow 'languages'), despite the fact that Deloitte is a huge company that could easily invest more into better effort on recruiting ads.

There are so many more, 80 results I found on Indeed just with 'tensorflow' and 'scrum', without even trying more generic search terms or looking on other sites.

Most likely you did not even search for this, or else just engaged with confirmation bias when one or two job ads didn't match the pattern.

But regardless, as anyone with experience in machine learning will tell you, it is extremely common for companies to try to require you to have front-end skills or train you to have them and then give you crap projects that are only aspirationally focused on machine learning, or just use machine learning as crappy hype signalling.

> "I fear your 'many times' is not backed up by reality."

No, you're just in a rush to use confirmation bias to defend scrum without deeply looking into the points that Scrum critics make. This claim is trivially disproved, even just from the links above.
