Not just automakers, and not just old fabs. Not everything needs the latest bleeding edge process. So, even then some of the old processes get updated to support larger wafers. Ex: brand new 65nm fab: https://www.electronicsweekly.com/news/business/bosch-opens-fab-2021-06/ https://www.electronicsweekly.com/news/business/bosch-opens-... So, 10-15 year ROI easy, and I'm guessing that might stretch even further as the trend to ever smaller nodes slows. AKA I'm betting 2nm doesn't look nearly as aged in 2040 as 90nm looks today.
