> Machine learning systems are also difficult to engineer because it can require substantial expertise in mathematics (e.g. linear algebra, statistics, multivariate analysis, measure theory, differential geometry, topology) to even understand what a machine learning algorithm is supposed to do and why it is thought to do it correctly. It's like Teen Talk Barbie.
