One specific thing that bots could help Icefrog solve: Many games are draft wins, i.e. a >90% chance of winning solely due to the heroes you've picked. There's almost no point in playing these games out for 20-40 minutes; it's boring for everyone involved.
This will always exist in dota, but being able to simulate hundreds of years of drafting + games could help reduce this.
