Scale / data set size tends to expose performance issues. But that's a good problem to have.
Yes, it would be great if all developers could write performant code, but let's face it - there's only so many hours in a day and days in a week. Developers already struggle to keep up with all the required knowledge. It's not that people don't want to be competent. We're building more and more complex things while expanding the number of people employed building software which means average skill level is probably slightly decreasing.
