> Can someone explain to me the rationale of investing in a product, marketing it, seeing that it drives consumers away from your product and erodes trust, and then you continue to invest at an accelerating rate?

Sure!

Google began investing heavily in AI (LLMs, actually) to catch up to the other frontier labs, which had already produced a product that was going to eviscerate Google Search (and therefore, Google ad revenue). They recognized this, and set about becoming a leader in the emerging field.

Is it not better to be a leader in the nascent industry that is poised to kill your profitability?

This is the same approach that Google took with smartphones. They saw Apple as a threat not because they had a product that was directly competing, but because they recognized that allowing Apple to monopolize mobile computing would put them in a position to take Google’s ad revenue — or allow them to extract rent in the form of payments to ensure Apple didn’t direct their users to a competing service. Android was not initially intended to be a revenue source, at least not most importantly. It was intended to limit the problem that Apple represented. Later, once Google had a large part of the market, they found ways to monetize the platform via both their ad network and an app store.

AI is no different. If Google does nothing, they lose. If they catch up and take the lead, they limit the size of the future threat and if all goes well, will be able to monetize their newfound market share down the road - but monetization is a problem for future Google. Today’s Google’s problem is getting the market share.
