And although it might be best of all to be Socrates satisfied, having both happiness and depth, we would give up some happiness in order to gain the depth.

Wisdom is not just knowing fundamental truths, if these are unconnected with the guidance of life or with a perspective on its meaning. If the deep truths physicists describe about the origin and functioning of the universe have little practical import and do not change our picture of the meaning of the universe and our place within it, then knowing them would not count as wisdom.

What else can matter to us, other than how our lives feel from the inside?

One way to determine if a view is inadequate is to check its consequences in particular cases, sometimes extreme ones, but if someone always decided what the result should be in any case by applying the given view itself, this would preclude discovering it did not correctly fit the case. Readers who hold they would plug in to the machine should notice whether their first impulse was not to do so, followed later by the thought that since only experiences could matter, the machine would be all right after all.

Taxation of earnings from labor is on a par with forced labor.

And although it might be best of all to be Socrates satisfied, having both happiness and depth, we would give up some happiness in order to gain the depth.

I think philosophers can do things akin to theoretical scientists, in that, having read about empirical data, they too can think of what hypotheses and theories might account for that data. So there's a continuity between philosophy and science in that way.
