It makes a real-world difference, there's no doubt about it. Hell, this is why governments issue arts funding. The return has virtually limitless potential in more than just the financial aspects. But it does take commitment, perseverance, and often, patience.
Despite these being crucial attributes to being a good developer, it's shocking how few (people and tech organizations) exhibit them.
They fail to understand that from the outside people don't see things Google does as sure bets.

Not everyone has low latency, high reliability fibre in their home, yet. If you have some crappy DSL or whatever then the experience isn’t great. Likewise if your WiFi signal is anything less than perfect!
And the people who do pay for the best internet connections are often those who don’t need Stadia, because they already have latest-generation consoles and gaming PCs?
I'm short on any attempt Google makes at being a media company.
