Grassroots-level adoption was key for things like Dropbox, IMHO - it solved a real need for individual people and it worked well and was easy to use. Same for Docker - developers adopted it in droves, and then enterprises followed.
Inrupt is trying to bootstrap a two-sided marketplace of sorts: product builders won't care until enough potential customers demand support for the "data pods", and regular people won't care until "data pods" solve real everyday problems for them.
Hopefully Inrupt's team has enough business-savvy people on it to find ways to gain traction to slog through some of the tough early stages of the product adoption cycle.
