USB-A seemed to be becoming the standard for built-in charging ports on furniture, wall outlets, and other household equipment, but newer devices increasingly use USB-C. What motivated the move from USB-A to USB-C, and are there any shortcomings that could lead to another connector replacing it soon? I'm considering whether to install outlets or other charging fixtures around my home, and I'd rather not choose something that becomes obsolete in a year or two.

The biggest improvement over USB-A is flexibility. USB-A was primarily a host-side connector, was awkward to insert, and generally supported less power and fewer functions. USB-C is smaller, works in either orientation, and was designed to work on both ends of a connection. It can carry substantially more power and bandwidth, although the exact limits depend on the USB, Power Delivery, DisplayPort, or Thunderbolt version being used.
For home upgrades, I’d be cautious about permanently installing USB charging ports in walls or furniture. The USB-C shape should remain useful for a long time, but built-in electronics can fail and cable capabilities are confusing. A regular outlet plus a replaceable, quality USB-C charger or power strip is easier to upgrade when charging standards change. If you do install USB-C outlets, choose a reputable model with enough power for modern phones, tablets, and laptops rather than assuming every USB-C port is equivalent.
Wireless charging may eventually replace cables for everyday phone charging, but it won’t replace wired connections for everything. Wired USB-C is still useful for fast charging, reliable data transfer, displays, and devices that need more power.
USB-C is very unlikely to become obsolete in the next year or two. The connector is compact, reversible, more versatile than USB-A, and can support power delivery, high-speed data, displays, and technologies such as Thunderbolt. Newer standards can improve the speed or charging capabilities while keeping the same physical connector, which makes USB-C much easier to maintain than replacing the entire plug every time.
The important distinction is that USB-C describes the connector, not necessarily what the cable can do. Two cables may look identical while supporting very different charging speeds, data rates, or video features.
USB-A will still be around for quite a while because of the enormous installed base, especially on computers, chargers, and older accessories. It will gradually become less common rather than disappearing overnight.
