At this point I don't think Wordpress is going to change their codebase into something more modern and secure. Is there any other easy to use blogging platform like it? PHP based because PHP is everywhere, based on a modern framework (symfony2, laravel, etc), jinja-like template system, support for databases other than mysql?
I was wondering if that site was some sort of aggregator and amazed that it would carry over the code examples so well from the actual article. This explains so much.
I think it's fine if some people get to live as long as they want. Not all of us desire it and not all of us would make good use of it. The people that do it can then decide to stop whatever is helping them stay alive when they no longer want to. I see no downsides to this.
