A few years ago I heard a lot of people worrying about how large buffers in our routers would cause latency problems. It all sounded very serious---like the end of the Internet. But I haven't heard any news for a couple years. Everything on the Wikipedia page looks old:

Is this something people are still concerned about? Were the original reports just hyperbole?

It is serious and remains so... but
Fixes have emerged (fq_codel, pie, cake) that are widely available in linux and linux derived gear -
which had spectacular results:

and pie was mandated as part of the docsis 3.1 std.
and standardization efforts of the new aqms is taking place at the ietf. For example, this RFC just emerged: https://tools.ietf.org/html/rfc7567 and there are other products of that working group nearing finalization.
While wifi and lte remain to be fixed, I sleep better knowing that the tide is turning.
