This isn't the first time I've seen this sentiment on HN, unfortunately. Some people seem to think it's just part of life to make false claims to investors, especially if you really, really believe you can succeed once you have enough cash.
Yes, it is.
#1: Saying you can do something you know you can't do #2: Saying you can do something you think or hope you can do #3: Saying you can do something you know you can do
While there is a human behavior difference between #1 and #2, you're still misleading your investors, right? Like I said, IANAL, so I can't say whether or not it constitutes fraud, but it is still dishonest IMO.
