Ralph Waldo Emerson is as relevant as always: "A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines."
Since then 500 million people or more have been taken out of poverty. They are competing with you for resources. That's why what was going on in the US in the 50s is no longer possible.
Because all masses accelerate at equal rates in a gravitational field either:
1) Inertial mass and gravitational mass are exactly equal without an explanation why
or
2) The acceleration is just an effect of a curvature of space.
Imagine two bodies thrown exactly Northward on a sphere. Although their paths are parallel they would approach each other, as if there was an acceleration. This acceleration would be the same whatever their mass is.
> For this portion I don't necessarily do TDD, because I remain unconvinced that writing unit tests first is inherently better than writing unit tests afterward.
I would argue that TDD doesn't imply writing unite tests - it's about writing any tests first.
If you have acceptance tests already written out, you're already doing TDD.
I'm probably much older than you, and I found the reduced travel or the alternative layouts much more important than speed. Your hands will thank you one day.
> SpaceX ahs yet to get us some place we haven't been in space, or at the very least one we have not been to in a long time.
It got us to a place where the cost of a rocket launch is 10 times less than it was before, and soon it will get us to 100 times less. It's just a matter of time that this is leveraged to bring us to new physical places.
> And equalizing SpaceX successes with Musk a person does way more than just rub me the wrong way.
He is the person that single-handedly made the decision to start a rocket company, decided on the initial architecture, hired the key people and finance the whole operation.
