Nothing currently, really. However, when I first joined the company I work at (as a Graduate Data Analyst) I wrote a recommendations engine in VBA.

It took about 5 minutes to chug through 3 months of sales data and produce a list of content -> content pairings & weights.

Then I discovered Python, cursed my manager, and the same algorithm ran in <1s on the same data.
