NAT doesn't solve the issues with IPv4, it merely delayed them. IPv6 is still the future, but everyone from ISP's to switch and router manufacturers have been dragging their feet on a real push to get us off IPv4. Hell, there are still modern switch platforms out there with full Layer 3 IPv4 support but IPv6 is curiously omitted - you've got to buy a bigger switch to get support for modern protocols (or an implementation that isn't totally gimped).

NAT does give you some valuable security features though

NAT is still ultimately a kludge for security, a stateful firewall is a much better solution and doesn’t interfere with the assumption that an IP address represents a device and not an entire corporate/home network.
