What are some interesting or exciting technologies that you have heard about recently which you think may be important for online privacy/security in the future?

Recently found out about Vless/Xray dedicated mobile proxies - security wise same as VPN, but speed and platform trust wise significantly better. You basically get encrypted traffic with mobile clean IP, CGNAT dedicated DNS and bunch of other things. As a result no bans, no detections and no logs. Superior than VPN. Multi routing eSIMs are cool shit too, not a shill but Voidmob com has it all for you online security. So yeah you should definitely check our their blogs and so on, they speak about some cool stuff.
