For the past two years, I have been exporting my images in WebP instead of JPG. If I share it online or send it by an email, I am pretty sure the other side will be able to see them.

I honestly think that all phones and even professional cameras should replace JPG with WEBP, we will have like 30% smaller photos.

The DNG format (for raw photos) allows JPEG XL compression (it used to allow only JPEG in the past). I wish some country made it mandatory for cameras to let user take photos in DNG (just like USB-C is mandatory in the EU).

I am happy that HEIC from Apple did not take off (as it was proprietary, protected by patents).
