Kuipers had a strong commitment to helping to preserve a record of threatened and endangered languages. As a 1998 article in The Economist put it, "Aert Kuipers ... went to Canada recently with the intention of locating and preserving American Indian languages. He came across dozens, some limited to a single valley, others spoken by only a few dozen people. He settled on one, learnt it and put together a dictionary and a primer. But by the time he had finished there was only one other speaker of the language left."[4] Kuipers responded to this in a letter that his arrival in Canada (nearly half a century earlier) was hardly "recently" and that The Economist may have conflated Squamish and Shuswap with regard to the "one speaker left" statement.[5]
