I remember Cuil when it launched. They were onto something great, made some pretty bold claims and in many ways were better than Google at search and look what happened to them? Nobody cared and they died in a huge internet tire fire. Sure the issues with poor results didn't help and people wanted them to succeed but lets be honest here, Cuil would have ended up like Bing (a few users but nothing to gloat about). People are too lazy to switch to anything new especially when it comes to search, it takes time to woo a user from another product that still does the job perfectly.
Having said that, this kid is 17 and he's done a f*cking amazing job. How many people can say at the age of 17 they built anything remotely cool like this? I'm sure some can, but not many. If he keeps on this path, he'll be achieving bigger things in his 20's and 30's than this and it'll be well-deserved. The interviewer was pretty bad though, he had no clue whatsoever an insult to the kid they were interviewing who deserves at least an interviewer with a remotely above average IQ.
