The thing is the most ludicrous ideas might also be the most brilliant ones, and the only way to know is in hindsight. I mean hell Google was a ridiculous idea in its day. Tesla was too in the beginning, and numerous other companies. Some ideas do require a lot of risk in form of up-front development for a shaky idea, but that's the only way to find out if that particular idea works. There are some ideas where you can simply throw shit on the wall until something sticks and iterate from there but there are also ideas that you have to go all in on. If someone says they're going to develop a "revolutionary new programming language" that will obsolete java/c# (or something) I'd roll my eyes and call bullshit, and in 99.9% cases it will be true, except for the one that isn't. Its up to every entrepreneur and venture capitalist to choose what kind of idea to bet on. I'd only hope that the entrepreneur picks something they're passionate about. You could say that you should at least be aware of the risk and scope of the idea your pursuing, but is that even true? Some might be better of not knowing or they'd never attempt it. As George Bernard Shaw famously said: "People who say it cannot be done should not interrupt those who are doing it."
