I didn't say it was a good idea, just that if Musk perceives it's a good idea then it makes sense why he would want to combine the two businesses.

It's widely reported that Musk is a majority shareholder of xAI and the controlling shareholder of SpaceX (close to 80% of voting shares). Not surprising that he would be looking to consolidate ownership under one entity especially if he perceives significant synergies (i.e., data centres in space).

Hopefully this will mean a lot more liquidity coming back into the venture ecosystem in the next year.

I could not disagree more - often times, especially if travelling with multiple people it is far more convenient, comfortable and can even be more affordable than taking public transport. While I agree that London has great public transport, Uber has been a game changer for myself and many people I know.

I took the list of 4 thousand odd cities from the UN statistics report of cities over 100k and then ran it through the batch geocoding site: http://www.findlatitudeandlongitude.com/ ... apart from that just old fashioned excel to calculate

Just some simple PHP / MySQL

How I built this: I pulled the population data from the UN statistics report on cities over 100k and then batch geocoded all of the cities (there was also a fair bit of data cleansing required). I then used a macro in excel to calculate the distance between every city pair (using Vincenty's formula) and uploaded the results to a database. Happy to share more if anyone is curious.
