ICO's are used for start ups to achieve funding to build a project. There is no need for an ICO if your project is completed. Therefor, saying that "no ICO has gone anywhere" doesn't make much sense. It's similar to saying that putting gas in your car is pointless, because it didn't get you to where you needed to go.
Gas and ICOs are fuel to make progress, they are not progress themselves.
If the project's that good then go get some VC funding and don't expect the saps that inhabit cryptoland to pay for it.
So far the only way you can make money out of ICOs is by offloading them on to other people with dollar signs in their eyes and it's probably always going to be that way. It's a fundamentally insulting and unsustainable model.
Not everything can be VC funded. For example, if you're a remote team, your chances of getting funded are already slim. Not everyone lives in Silicon Valley or the US. ICOs are a genuinely novel and important way to fund projects.
That being said, yes, there is a lot of abuse and 99% of the them will likely fail. But lets not throw the baby away with the bathwater.
