I get stuck in understanding the way the author phrases his thoughts in this blog:
We’ve already bet the kitchen sink on linear algebra and differential functions, we might as well just go all in and bet the farm on complex analysis.
I can grasp the point of the sentence but am not familiar with the analogy. I conjecture he means mainly that we can just take a plunge into unknown waters(complex analysis) since we already have benefited from the less powerful linear algebra and differential functions just for real numbers(real analysis).
Am I wrong? And how can I comprehend the "bet the kitchen sink on sth" and "bet the farm on sth else"?
