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.
