The foldable display technology has still a long way to go to achieve absolute practicality. Royole's Flexpai is a great innovation but still far from practical in terms of everyday use. As MKBHD said, there are very few use-cases for the technology. Additionally, the "disguised" folding phone from Samsung and "leaks" of Xiaomi's own foldable phone do not look so promising either. We'll have to wait until the Unpacked event on 20th February where it is rumored that Samsung will be revealing the foldable phone in all its glory. All in all, since the technology is in its first generation, there's still a lot of rooms for improvement. However, I'm still pumped for it and hope the OEMs are able to truly wow the consumers.
