But ultimately, I think that good design is typically subtractive, not additive. The best digital products improve our lives--our lives in the physical world--while sucking up as little of our attention, mental effort, and personal information as possible.
I think it's only a matter of time before we see these attitudes become more prevalent (precisely because they are controversial/reactionary), and the general design ethos of Silicon Valley shifts as a result.
One of the key tensions of the near future may be between minimalism and maximalism in this way: should we throw more and more computation power at every single "problem", brute-forcing a solution to each for its own sake? Or should we optimize, and find the smallest, least intrusive, most elegant and simplest solution? I know which one sounds better to me. But will that drive business revenue? We'll see.
Perhaps more importantly though, at a certain point--by creating so much digital detritus and complexity, our brute-force solutions and ever-present computation create a new set of problems (such as the need to filter information aggressively to get any useful value from it--which is what minimalism is all about). So maybe this is just the realization of that. We need a new layer on top of the computation infrastructure to __reduce__, to complete our maximalist designs. Either way, interesting.
