I don't see anyone writing that ML/DS is a lot harder than a typical SWE and results are a lot less visible for a VERY long period of time. A lot of the time you could train model prepare pipeline and test enviroment for 3-6 months before you get good enough result to push it into production. And it can get extremely stressful rly fast if you care about that, because not every model is good enough for production so o…

IME the core issue here is that there are far more SWE jobs than ML/DS jobs, which leads to a far greater variety of SWE jobs, which means people are better able to find SWEs jobs where they are able to find a job that matches their job environment. If you want to coast, there are SWE jobs for that. If you want to work 12 hour days on the bleeding edge, there are jobs for that as well.

Some of the the major job challenges in ML/DS are that the field is new, the number of jobs are far fewer than SWEs, the teams are small, and the people who can exert control of you have wildly unrealistic expectations of what it takes to build a useful model. So it's easier to land in a crappy job where stakeholders add to your stress because you are not "delivering" according to their definition of "I thought ML would solve all my business problems in 2 weeks."

I personally prefer ML/DS to what I see a lot of SWEs do. Yes, it can take months to get something working (or maybe it will fail after all that effort), but I'm also involved in the end to end of what I'm building and I get be part of defining the the "what", "why", and "how" and not just crank out yet another story on a Kanban board. What really helps me in my job is having a management chain that pushes back and educates stakeholders on why things take time and why that time is required to have a certain level of quality.

There are plenty of SWEs (on HN and elsewhere) who say they feel like factory workers. Somebody else makes a bunch of decisions and the SWEs simply churn out features and stories. So the quick wins turn into an endless flood of drudgery, just like how when you learn to fix a toilet you feel great, but if you fix 20 toilets a day, it probably becomes monotonous pretty quickly.

>Where will that leave people trying for either ML engineer or more data analysis focused DS roles? Or even just everyday utility scripting/automating powers? Can even the latter two can be largely replaced by hybrid finetuned multi modal language/code models. I feel a bit lost and like I have wasted my time.

IME most people have a bit of culture shock when they first get an ML/DS role. When you learn ML/DS, there's a huge focus on the coding and mathematical parts of the job, and not on much else. When you get a job, suddenly you're exposed to everything else and you realize why every data scientist says that ML is only a tiny part of their job.

There's a lot of variety in DS jobs, but one of the things I try to explain (when somebody asks me) is that the real skill of every DS job I've had is "Taking a vaguely defined business problem and working with stakeholders to come up with a solution that happens to use code, math, and charts as the path to that solution." In reality, to succeed in as a Data Scientist, you have act like a Product Manager+Product Owner+Data Analyst+Software Engineer+Data Engineer+Data SME.

This is why so many attempts at "We can make your Business People Data Scientists" products haven't taken over. You might be able to take over some of the boring parts (e.g. AutoML, doing the parts that Data Scientists hated doing anyway), but I've never seen a piece of software that could tell the business users that they don't have the right data to measure what they are trying to measure.

I've even seen commercial AutoML solutions lead to business people realizing they need to hire Data Scientists. This is because once you use AutoML, you realize you need somebody who actually understands the data and the process to really trust the results.

If "hybrid finetuned multi modal language/code models" can replace what competent people in ML/DS can do, that technology is going to replace a lot more professions than just ML/DS. There's going to be a job apocalypse for lots of professions, including SWEs.

I think from a career standpoint, ML/DS is a bit of a mess because it's a new field and businesses are still trying to figure out the best way to get value out of it. So there are a lot of pain points for people working in the field. Compare that with Software Engineer, which is older and a bit more mature. But I still think ML/DS is a field worth getting into if you can sort through the noise of which jobs are good and which are crap.

Despite having a "unicorn" skillset (soft-skills, advanced degree, domain experience, and SWE experience), I make about as much as a vanilla SWE.

Agreed. I actually like that in DS you can have a job where you are involved in the end-to-end of a business problem and that you need to have a mix of skills (e.g. Act like a Product Manager and an Engineer) to succeed. And it's not just "Today I get to crank out yet another tile on the Kanban board."
