As an entrepreneur myself, I would agree with their strategy. First, keep your monetary burn rate low by not making your overhead too large and too quickly. Second, make sure the market is truly what the hype is saying - which AI seems rather hollow to me. The AI market opportunities that everyone are going after already has players in those high value arenas such as IBM Watson (think: medical diagnoses, data analyses, financial market analyses, etc.). Third, once a good solid market has been identified, go after that market and don't do the usual startup goof where you chase everything with starry eyed hubris and waste your startup money.
Mature incubator programs always make sure that their startups have done a proper market study and that there is not too much competition to cause ultra high risk of competitive failure. Investment groups such as Berkshire Hathaway use these solid principles. Even on Shark tank, you will see the seasoned investors stay away from anyone who has not done their market due diligence.
For AI, It is going to be difficult to get enough of a return on $100B's of investment to pay it back in a reasonable amount time. Most investors are not going to be pleased to find a 5-10 year wait on returns. There are too many other opportunities out there with much shorter market return times, giving VCs chances to invest in multiple cycles with their money and amplify their returns.
