WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
We made abstractions successfully, world changing abstractions.
Do the NAND to Tetris course and see that tech is abstractions on top of abstractions. Electronics today is frequently represented by code. Check out Verilog or VHDL.

Where electronics stayed interesting is in the realm where code meets reality -> robotics and art.
Playing with LED's, robotics competitions, quad copters, cosplay. Maybe adjacent to SDR. Raspberry Pi's and Arduinos.

There is also the greater cultures: Maker culture and hacker culture. Maker Faire is super interesting and has many many attendees.
I would say that in America, it is harder to work with electronics because the number of maker spaces and places you could buy parts (RadioShack/Fry's) greatly diminished, but afluent folks can definitely have an electronics hobby supplied by online vendors.
