Rossmann had a doomer-pill moment, he worries repair could be going away and "undo his legacy" https://farside.link/invidious/watch?v=oMPxr7I90JM
His argument for this is that he thinks that machine-capital for producing tech-gadgets will get optimized to the point of being fully depreciated after a production-run is complete. He thinks that this would negate the economic viability for making spare parts of letting the production machine run a little longer because parts can be sold for profit as well. However most production machine-capital isn't product specific anymore, save for a few specialist components like plastic-molds. Most of the stuff in a production line gets re-used for other stuff once a product-batch has completed. There are costs involved in puzzling together a modular production line, and because of that the economic viability to getting extra profits off a line from spare-parts remains.
Repairing tech will not go away, because it costs less labor to repair than to build new. You have to consider more than just the last manufacturing step. The entire supply-line that precedes that last step does not have to spring into action if you repair, but it does if you build new instead. The age of just throwing shit out and buying new, even for tiny defects, was only viable because for a limited time there was near endless cheap labor in Asia.
Repairing also reduces waste-streams and resource consumption. The cost of those are going to go up, new resource extraction will get more expensive, considering that you either have to dig deeper or go into space, recycling also isn't free and it's probably going to get more expensive to throw shit out because dealing with trash gets harder too.
If you look at the technology design from the perspective of a physicist, a machine is a collection of matter with low internal entropy. If you use the machine the internal entropy increases. If you don't want the machine to fail, you have to somehow remove "chaos-energy". That can be done in the form of cooling. But one particularly effective way is to replace wear-parts, where the "chaos-energy" is concentrated into.
There are structural developments that favor repair too. The biggest hindrance for repair has always been managing parts logistics, but computer-data-bases and object-storage-automation have removed that hindrance, managing a gigantic catalogue of goods is now a marginal cost.
The tech-giants of today that are pushing for gadget-obsolescence are going to look like dinosaurs in a decade. It's so disheartening to see people like Rossmann waver when the new dawn of repair-ability is so close.
