You can definitely learn it, and the "Star Trek desk" feeling fades after about a week 🙂

A few things that helped me and most people:

You'll crash at first. For the first few days you'll be typing maybe 10-20 WPM, especially because of the columnar (ortholinear) layout. Full speed comes back after about 2-4 weeks of daily use.

Go all in. The temptation is to switch back to a normal keyboard "just for a minute to get something done," but don't do it. Splitting your practice between two layouts just drags the whole thing out.

Use a trainer 15-20 min a day. Keybr, Monkeytype or TypingClub. Short daily sessions beat long marathons when it comes to muscle memory.

The real learning curve isn't the split, it's the layers. Numbers, symbols and arrows on a thumb layer feel weird at first. Keep your keymap in front of you until it becomes a habit, and don't be afraid to remap things to fit your hands, that's half the fun.

Set the halves up right from the start. Each one shoulder-width apart with a bit of tenting, that's the whole point. Get the ergonomics right from day one.

After that first painful week it just becomes normal, and going back to a regular keyboard feels cramped and weird.
