Unfortunately the parent link is to a second hand source rather than a direct quote. The way Slate frames Page's answer makes it seem lacking in empathy to people alive today who suffer. Maybe it is just Slate's framing, but reading the article makes it sound like Page's intention in saying he would leave his money to Elon Musk is to say that Elon Musk is doing more for the world than people curing polio or building schools.
Which he has every right to believe, just as I believe saying something like that is lacking in empathy.
Well, I won't argue against you have the right to say that. Heck, I might even agree with you, pending further discussion.
My only point is that Page's position is not implicitly "bad" or undesirable, in that he clearly is concerned about helping the world - he just has his own strategy for how to do it.
