Who's to say that the minds they're building aren't more suitable for a future environment? You're assuming the future is like the past, which is most assuredly won't be.
Building minds? They aren't building minds; evolution is what built minds, and it hasn't had time to adapt to this situation. Modern media is exploiting bugs in the mind's structure for profit, and these companies are leaving plenty of damage in their wake.
If the future is passive consumption of propaganda and marketing content masquerading as "entertainment", you can count me out. I'll go chop wood and raise chickens while I watch for the system to collapse under its own weight.
I truly hope that being addicted to instant gratification via a dopamine response doesn't make one more suited for future environments. I can't see how that would be healthy or productive
