The simpler explanation seems more correct here — there was a lot of product fluff and a lot of headcount allocated to build that fluff.
The fact that one division of Google is wildly profitable does not exempt other parts of the company from criticism of their financially dubious choices.
I'll assume the former and try again. Maybe you didn't realize I'm not the person you originally replied to?
If a company is profitable, they have funds. The funds generated by the profits, can be used to fund additional internal projects. If the bucket of funds from profits gets ridiculously large, then it may begin to be used for vanity projects, like gutting an AI company, or building a gold statue of the founder. It seems reasonable to call companies spending on mostly-useless excesses "overfunded".
Stop looking at the entire world through the eyes of VC, because it doesn't work.
You're not funding google by paying for youtube, you're buying a service.
You didn't "overfund" your pizza shop that hired a stripper for friday night vibes, and neither did 99.99% of customers that paid google for their service offerings.
You just bought a pizza. Put down the VC podcasts
That's fine. I'm going to continue referring to corporations that blow lots of money on random intra-industry dick measuring matches because they can as "overfunded", and you can continue expressing your opinion to anyone who will listen that this one person on the internet used an idiom that you think is dumb because it implies something other than "that person profited, therefore they did something right and therefore whatever they do with that money is correct and intelligent and never ever wasteful or dumb."
As a bystander and outsider it is hard to isolate the value igniting behaviour from the moonshot behaviour. Shareholders love to gut a business of its risk taking and excess behaviour for predictable and inflated margins (and dividends) but the past 20+ years of our megacap companies is that they have continued to "innovate" in spite of all their inefficiencies.
I always have a chuckle when I recall how shareholders tried to oust Zuck for buying Instagram for 1B...
These vanity hires do seem frothy and reminiscent of dotcom style behaviour. But "AI" clearly will be game changing much like the internet was, and who at this stage can say what is worth recruiting people at the forefront of commercialising the tech right now
