I was wondering if more sites will start to drift to a system where they require you to be logged in to an account attached to a SIM card in some ways.

I feel like accounts that require phone verification are already similar in that they require a some cost to access. It obviously wouldn't stop a large corporation from buying up thousands of numbers if they needed it for a specific purpose, but it would be prohibitively expensive for most to try this.

The benefit of the SIM system is it actually costs zero for people since they already have a cell phone.

When you use a captcha, you presumably want to defeat someone curling your CreatePost endpoint, not just make it more annoying to do it at only botnet scale. This captcha still lets all traffic through. Except now you waste the battery of honest users. Even HN proponents of the idea don't use it on their own sites.

I rather see something like anubis than some unsolveable captcha. I never understood the battery-argument, I recon my screen uses more energy during pow-solving than it takes my phone to solve these pows.

So would bad actors. Which is why everyone uses normal captchas and not mere PoW.

PoW is the easiest captcha to beat.

Such site is better provide some unique service no one else can.

There is no way I am sharing my phone number with random sites unless I absolutely have to, I get enough spam & scam already, and tracking potential is enormous.

I hope we move away from SIM cards - they'll require SIM based auth checks and low paid staff at cell phone companies will happily give away my SIM card to another phone to get a kickback from robbing people.
