As for Dota, indeed the broader game was designed and is constantly updated to be an intellectual challenge. Cheese strategies exists. When discovered, game rebalances are conducted to ensure players don't settle in on brute force exploits.
In just 5-10min of watching some of the matches, I already know a handful of characters that would 'break the bot' on this 5 bot ensemble. This is powered by human intellect (the truly significant part). The bots trained across time horizons greater than a human lifetime in this unorthodox and slanted arrangement. Human beings seasoned on a more well rounded and balance game are then thrown to the bots and showcased. I know who would be sold on this and its not your average Dota player.
Again, the fact that it is possible to 'break the bot' examples that the whole thing is a charade. I have no doubt they might have gained some experienced/understanding with engineering this solution but the actual result is lipstick on a 'backpropaganda' pig.
More fundamental deep research and less theatrics is in order. I'd also advise becoming seasoned in the thinking behind a particular game if you're trying to test and develop an artificial form of intelligence to navigate it and beyond.
People need to start doing more critical analysis of their own and stop relying on commercialized and biased information and commentary when settling on an viewpoint. Watching others play only gets you so far in understanding. When you play and you see what I'm saying for yourself, you can skim through the provided clips and understand exactly what's going on.
The fact that this continues to get hyped up vs someone stating what's going on is plain sad.
