"Seriously, we don’t need smartphone-controlled X" will always give way to "but if it doesn't exist, we'll have the market to ourselves," and so you'll continue to see "smartphone-controlled X"s being created and successfully funded, as niches still have profit margins. There's really no point to the protestations anymore. "Smart X" is the new novelty modifier, and we've seen these come and go before. Just acknowledge it as a trend, purchase the ones you always had an interest in and believe a good product exists for, and forget about trying to dissuade the average consumer from doing what they're going to do anyways.
