What exactly is Data Science?

Data Science and DevOps are both just labels for things people have been doing under more mundane terms for 40-odd years.

Even Machine Learning is just a trendy buzzword for what used to be called Predictive Statistics.

I did stats before data science was a thing, and then ran a data science team afterwards, and it's dramatically different.

I've never seen any stats text book or course discuss techniques for dealing with large amounts of data to any significant level, but in data science that is a core part of what you do.

I ran production systems before DevOps and after. Again, it's very different - prior to devops, there was no emphasis at all about using software engineering techniques to manage and deploy software. The most you'd get was some scripts maybe kept in source control if you were lucky.

Now I run an AI company, and a key part of the ML we use involves generating structured text files from images. I guess predictive statistics is technically a correct label, but the tools and techniques are so dramatically different that that thinking of them as separate fields is more correct than incorrect.

I struggled for years to understand DevOps because I couldn’t see what was different from how I worked already... the answer was nothing :-)

DevOps gave a name to what your were doing, that other sysadmins and product devs did not. Is that bad?
