Yup, this. I found many ex-Googlers who just don't know how to count up. In the past, "we don't know how to count that low" was a valid joke, but, these days, it seems like a lot of young engineers don't really understand how things work beneath their feet. Every level from 1 to 1k to 1m to 1b is a unique problem, but these kids only learnt how to float above the clouds.
