Speaking as someone who has been a long time coder in C and Java, I think the point he makes about checking errors is BS. You have to handle exception in Java and you're perfectly free to consider all the possible failure paths if you want though typically you'll handle the ones you can sensibly do something about and ignore the rest (i.e.: log or just fail outright depending on context). I do NOT miss the C world where you have to handle the results of every single function call if you want to be safe. The exception handling approach IMO is generally superior - the normal code executes simply and the exception handling code gathers all the exception cases together. Much better than interspersing both and especially better than handling the same error 10 times in a row rather than just doing it once. That said, I love C. It's a very simple language and that's a virtue.
