It is strange because this is a big announcement, that is concrete with real money and people (more soon to be announced). By Elon Musk. But there doesn't seem to be much love for him by the press.

Is it because Elon offended the press few weeks ago? I don't understand why press thinks it is above some criticism?

I suspect publicity created by this will easy recoup all expenses.

How?

When you have billions it's irrelevant, no more than the average joe dropping $10k on a holiday

Slight correction: when you have billions, but found your projects in big part by government subsidies.

If you pay taxes in USA, you partially own tiny bit of every single conpany other than x/paypal that Musk ever -funded-

Slight correction: This is Maezawa's money that is been discussed here.

Indeed, this is someone who's happy to spend $100m on a picture.
