No, 100 years ago there was all of this brand new fundamental science and technology and it was easy to imagine things that could be... today we're in the late stages of filling in all the gaps, we've explored all of the spaces and the most exciting things we could imagine are the things we already have working somewhat better than they already do. The scifi that gets made is either fantasy (this will never exist because it's impossible) or retro-futurism (old scifi imagining, essentially, the present).
