A good presentation, but a bit misleading in its comparisons to "esters". Esters are a huge family with a great variation in properties, so any comparisons really should identify the ester he is comparing to, and note that the comparisons do not apply to all esters.
For example, many POEs have better oxidative stability and low coking tendencies at very high temperatures than these ANs, and some have equal hydrolytic stability. Many esters used in lubrication also have better VIs, lubricity, and low temperature properties, and POEs are more versality in custom designing a balance of properties.
Both ANs and esters, of course, have their place in lubricants and either may prove better in a given application or formulation. Making broad statements about broad chemical families, however, doesn't tell a complete story.
