The internet is still largely IPv4 based, even though IPv6 has allegedly 
been around almost as long as OSI implementations.

Retail ISPs back then liked cheap stuff and cheap staff. Mostly they 
still do. IPv4 was cheap. Browsers were cheap. Expertise and training? 
Hmmm, no, we don't do that, it costs too much.

IPv4 is still cheap (for ISPs). IPv4's ongoing impact on end users 
varies, but apparently things like CGNAT (widely seen in the mobile 
world) are not much fun for end users who want to go slightly off 
mainstream.

In the user-visible world, insecure browsers (and insecure email, and 
...) are now a huge contributor to IT insecurity. But never mind, 
Tikstabook will sort it. Perhaps.

Also at the application level, prior to proprietary non-standards-based 
web-GUI-based email taking over the world, the main setup that the IP 
world could offer was a teletype-era mail setup (POP/SMTP) which needed 
dozens of band-aids to be added before it was actually anything like 
usable, especially in a multiplatform environment. That's before we even 
get into "advanced" higher-layer topics like authentication, 
authorization, and optional extras such as (e.g. for email) secure 
delivery, non-repudiation, etc.

Still I guess some people must see it as progress.
