Maybe I'm just old but I bought some Eneloop rechargable batteries in 2008 and then some more Amazon branded rechargable batteries in like 2015 and a single charger and they've been powering devices consistently for over a decade. Half of my toddler's toys run on AA or AAA batteries. Calling them old fashioned feels like complaining the form factor of a 12 oz/330ml soda can is old; technically you're right but it's been around for 50 years because it works exceptionally well.

>AA batteries (which are generally not rechargeable)

I can't recall the last time I saw single use batteries in use, except maybe in a brand new remote control bundled with a TV, which was quickly swapped for rechargable. I don't even think of this most months, from where I'm siting I can see my battery chager and there's two sets of AA and a set of AAA sitting on there fully charged, ready to go. I think I paid $12 for the charger in 2008, very low barrier to entry.
