Is CI outdated ?

I have a web apps developed by using Codeigniter 3. I try to sell it to government. But, before doing that, I showed it to my friends. Here are the responses :

"CI ? LOL.. Why not using Laravel ?"
"CI Is outdated. Please use another framework before selling it"
"CI has no future."

and others negative responses.. Should I move to Laravel ? Or just using CI 3 ?
