IDEs are I think a good example. There were IDEs in the 80s and 90s but they are very different from now. For example back then they did not index files at startup since there was no function for that (like "find references"). These days IDEs provide a lot of "intelligence" and static analysis for which you need memory, a lot of reads and processing. So yeah, I guess VS got slower but it's because it's now doing much more (useful) things.
