I won't argue about sexiest way but sure the most expensive. Some assessment broke down you need some 30 years of continues use to break even, that is excluding cost of battery and other accessories, so assuming nothing ever breaks in 30 years.

Good luck with that, because at this rate you can literally sell snakesoil and claim it works. Take any group of say 10,000 people, have them use it for the rest of their lives, I guarantee you find few people who miraculously got some sort of disease cured.

- Who said the initial crewed missions to Mars would be a fancy sort of cruise trip?

Musk said that during the first presentation regarding the trip.

Why would I want my roof to be sexy?

"Why would I want my clothes to be sexy?"

"Why would I want my kitchen to be sexy?"

"Why would I want my car to be sexy?"

Oh right because tech people just assume that sexy is an adjective that makes everything better. I remember hearing this associated with Ruby on Rails at one point and realizing I might not fit in with this whole scene.

It's commonly taken to mean "visually appealing". I never use it in that sense, but I don't find it difficult to translate from those who do.

I appreciate that you aren’t propagating this usage.
