It's very simple: the EV market is growing at around 20% globally this year. That's despite all the whining from some manufacturers that there's no demand for EVs. Which is true but only for their EVs. Because they simply aren't good enough. Too expensive to make. Not comparing well to cheaper competitors, etc. Take your pick. They aren't selling well and that's a problem for the manufacturers that are making them. But it's not true for other manufacturers that are growing. Even in the US the EV market is expanding.
Either way, that EV market growth is in the context of an overall car market that isn't growing anywhere near 20%. So, EVs are growing at the expense of legacy car makers. Their market share is effectively shrinking. By about 1/5th a year. They have cost related to that for downsizing production capacity, getting rid of staff (and the associated compensation packages), dealing with related strikes, etc. Many of these companies won't make it. It would take many billions in $s of investment in R&D, new products, new production facilities, etc. And with many of these companies slowing down those investments, it's not going to magically improve for them. It's a death spiral.
There are also no signs of EV market growth slowing down much further. With price parity effectively there if you have access to BYDs (which much of the world does), it's game over for ICE.
Now it’s just a way to make the number perpetually go up, sucking every last drop of value out of the system.
Plus the complete lack of vision or strategy from Google’s senior leadership.
So how does Adtech generate more and more revenue and sells more and more ads year on year?
Simple answer - Fraud.
