So sure, sharing an IP amongst many people may help a little, but we've already ran out _today_. There are people living right now that will _never_ be able to access the internet or make a website because of this.
One example: Digital Ocean have a cap on the number of servers they can run at one time due to the fact each droplet gets a unique v4.
V4 is dead, time for money to be spent in the right places :)
I’d generally focus on the cost of losing P2P and the continuing rise in the number of devices the average person uses.
Well, if that's the only problem then I think we can tone down the sense of urgency because 1) there are much, much bigger problems to deal with in life and 2) the web has become a shithole with its growth in popularity.
That's my opinion of course. I'm guessing that you think Internet access and Internet publishing are basic rights of human existence, but I would disagree with that.
I don't know you, but I bet given enough information I can find ways the internet are vital to your way of life.
