We are on the comment section about an AI conference and up until the last few years material/hardware costs for computer science research was very cheap compare to other sciences like medicine, biology etc. where they use bespoke instruments and materials. In CS, up until very recently, all you needed was a good consumer PC for each grad student that lasted for many years. Nowadays GPU clusters are more needed but funding is generally not keeping up with that, so even good university labs are way underresourced on this front.
