Unless you build from scratch, and white box stores suddenly start selling a 48v version of every standard household appliance (with industrial supply chain to support that market), inverters are not going anywhere.
The only place it makes sense is personal tech and computing, where USB chargers are cheap and ubiquitous, with technology replacement in 2-5 years instead of 5-10 for standard appliances.
it would probably slowly start coming out as dual ac and dc connections and start with "garage appliances" like your laundry, central ac / vac and car charger since the garage is the cheapest place to wire something into.
I read an article about a house that was converted to use DC instead of AC as a trial. The most surprising part to me was that most household appliances simply kept working because they already contain a AC/DC rectifier anyway which works fine if you connect it to DC.
I run my garden tools and shed on a 1.2kVA 12V inverter, bought for pennies off eBay. It's just about enough to run my little "lunchbox" flux-core welder on a low enough setting to do thin metal and tubing, perfect for sticking exhaust pipes and such together.
