Sure, it's fine to run a technology business like Waymo at a loss. It's even fine to do so for many years while the technology is allowed to mature into something profitable.Wow...so if a company does not make a profit in trial phase why scale it? So Uber..which took years and years and years to make first profit should have shut down to start with. Google...same thing, should never have pushed forward. Intel..no...stupid idea. Tesla..terrible idea. FSD by Tesla which is a money losing pig right now...yeah shut that down. SpaceX...shut it down.
I agree with you that Waymo is going to focus on the USA at first. I disagree on the mapping, the maps are constantly updated as the vehicles drive and Tesla may very well find themselves using maps. I'd be very careful about making blanket statements such as that.
The only lunacy I see is to assume that Waymo won't have 50k robotaxis. Its clear that's what they plan to launch. It's clear that they go from a to b to c to d, etc etc. They solved FSD first, is it geofenced, yes. However, today you can get in a waymo in phoenix and drive across town. Same thing in San Fran. Austin, LA, and somewhere else coming soon. They plan to offer RT in the top Uber cities in the USA and then see where it goes. I'm bookmarking this post because I'd like to return to it in 2 years and we'll see where things sit. FYI, you sound like the TeslaQ people that said EVs don't work and nobody wanted them and tesla was a scam.
Waymo's problem is that there just is no clear path to profitability. Waymo's hardware costs are too high and more importantly, Waymo's operational costs are too high.
Scaling will help with the hardware costs to a point. But Waymo's technology has to massively improve before it will address operational costs. Otherwise, more scaling will just lead to more losses.
That's why Waymo won't have 50k robotaxis any time soon.
