3 kids of my own, lost a lot of sleep with them early on until they got into a workable routine. I advise to be careful of mistaking the battle for the campaign. You want to win the campaign, even if it means losing some battles. In this case, turning to co-sleep is attractive because it feels like you're winning the sleep battle easily. However, in the campaign that is life with your children, this is a losing strategy if the co-sleeping has a negative effect on your relationship with your spouse, particularly when it comes to intimacy. Remember that your kids also need your marriage to work well over decades to come.
Similarly, giving in to defuse a tantrum is a short term win that will cost you over the long run as your child becomes insufferable, self-centred, and fails to achieve age-appropriate levels of maturity.
question 1. Does the introduction of the first iPhone divide the history of the mobile phone into two distinct, and radically different, segments (say Before iPhone (BI) and After iPhone (AI)?
question 2. Do AI-era smartphones represent a major augmentation of the capabilities of average human beings?
When answering question 2, step out of any jaded First World bubble you might find yourself in and consider people in all parts of the world.
Recycling does indeed work, as proven by the last few billion years on this planet - literally everything that ever was on the Earth is either still around or has been recycled over and over. It is the concept of 'waste' - introduced by a recently arrived species - that doesn't work. Unless there is some infinitely expandable place to put it, producing ANY amount of unusable or unrecyclable waste that accumulates will at some point in the future become a problem. This is math that even the most rabid Koch bros follower can't argue with.
Maybe it's old hat for phone devs. But the fact is this is the _iPhone_ prototype - a major inflection point in not just mobile phone history, but in world history. So even if its physical form is nothing special, its significance is.
Your life is literally made up of the things you pay attention to. If those are happy things, you will probably be more happy than not, and vice-versa. Money gives you a choice about what to pay attention to. If you are in a survival or starvation situation, you will be forced to pay attention to surviving / eating. Not having a choice about what you can pay attention to means your life is defined by outside forces. If these align with what you like, you can be happy in those situations; but if not, you will struggle.
