I haven't seen the number of man/hours in your reasoning...
You dont need man/hours when measuring the velocity of a team.
Currently CiG is a full capacity (arent there like 500 people working for them ?) and bleeding tens of millions $ each year.
With that capacity, their full speed full content pipeline delivery was put to the test with Microtech. This is the base of the estimate for that velocity. I am being generous because that was their best performance overall. So far, Pyro matches the expectations in terms of velocity as they have been obviously not delivering it any faster, and we have to remember they have a head start with one already complete planet (Delamar). The 98 other systems will follow.
Pre-alpha prototypes of Tesla 3 from 2007 to 2015 released = less than 1000. So it's 125 cars / years = one car every 3 days. With 500 000 pre-orders, Tesla will be able to deliver the last one in the year 6130
Flawed comparison. At that time Tesla were ramping up production, and actually building their factories. It was pretty well known and documented. Oh and as opposed to CiG, they actually delivered, and not one but multiple products so there are worlds of difference there. And working products, too (*). And again they are still not at full capacity, unlike CiG who will celebrate the 10th anniversary of this project in December this year and have pretty much hired everyone quite a few years ago.
Software doesnt take a whole decade to build, nothing does in software realm, even operating systems, this is completely ludicrous to think they are still in the early phases of the project. They are now with a huge pile of unmaintainable code that has spaghetti like ramifications just everywhere and touching one part will make another unrelated part crumble entirely. That's the clear sign of a bloated, soon to be replaced project usually with proper management. Again by comparison (and car comparisons with software are always, always completely irrelevant but let's entertain your idea a bit) Tesla have a fresh production line, fresh products they can improve upon, a very nice expanding market with way more demand than they can offer, and a very solid technological base (and dubious marketing tactics too...). Oh and again, working products on the market.
(*) to be nice and forum-friendly i'd limit myself to say if Tesla cars worked as good as SC game/physics engine, there would be a lot of entertaining videos around the Net...
Isnt it rather several years? If they ever are able to scramble tocether another system that will be it for another couple years.
Yep, that's about it, if you count the average of 5 planets and their moons.
