Literally the only pro-tech argument that I can think of from the top of my head is that rapid de-technologization would drastically increase the chances of invasions of our homelands. For example, if America ceded its nuclear arsenal then China could simply obliterate America while the rest of the world meekly watches in horror of what China could do to all of the lesser powers.

Removing these practical considerations I'm overwhelmingly partial to Gemeinschaft over Gesellschaft, i.e. modern society. The proliferation of technology has been one of our biggest problems. Ideological multiracialism wouldn't exist without planes and modern ships "shrinking" or "connecting" the world. No Ebola, HIV, Spanish Flu or Covid, either, all of which are imported. Life expectancy in Africa was around 30 precolonialism, but is prolonged by that racist White man medicine, which now means that four billion blax is a serious possibility. People wouldn't dream of "seeking a better life in the West" because they only develop these ideas through comparing what they see on television or the internet (through phones and computers) to the cesspool around them. It goes without saying that most of these inventions are overwhelmingly products of White ingenuity used in ways which harm and will continue to harm the descendants of their creators.
