"now, what?", what?

That 42 is the sum of three cubes.

> Why did we look for a solution in the first place?

They did. I do not believe that you were involved.

> How is it important that a number can be a sum of three cubes?

People like things for their own sake. How is it important to have sex or drink a beer? Same thing. Also math has this uncanny tendency to turn out to be useful where you least expect it. Consider the primes. For a long time people might have asked the same question you are asking here, and yet now they are central in encryption and thus the digital finance market. Could not find a more capitalistic and materialistic use if you tried.

Why are you so bitter? I asked this genuinely. I doubt PhD+ people do that type of research "just for fun", or do that like someone like me drinks a beer. Someone answered elaborately, and I'm glad they did. Thanks anyway.

I don't know, it's just how I am.

Well you'd be surprised. All the professional mathematicians I know do math for its own sake. Some amateurs also do it "just for fun", as you say.

> Someone answered elaborately, and I'm glad they did. Thanks anyway.

A bigger person than me, especially considering the tone of your question.
