Nothing will happen until psychedelics are rescheduled. It's a travesty that even the "natural" tryptamines (psilocybin/psilocin and DMT) can't be researched more easily.
The main benefit of rescheduling will likely be through easier access to government funding and funding from large foundations.
If you’re very wealthy, you can fund psychedelic research that interests you today - again, the scheduling is not close to being the main limiting factor.
