One of my pet ideas is a new programmer's editor that uses proportionally as much compute resources as Emacs did in the late-80s. An amount of computing that would show up as a major line item on your department's timesharing bill.

1000 cores costs around $50/hr, so if it boosted my productivity measurably it'd be worth it. Searching all public github code for strings matching around my cursor seems like the sort of thing these 1000 cores should be doing.
