My understanding of BGP is that it’s so old (and was relatively well designed) that it could now be considered an arcane magic once widespread but now only known by some old wizards.

The problem with both is that they were both designed long ago, without much regard to bad actors. They have been around so long replacing would be a herculean effort.

For some reason whenever I interview very junior candidates - every _single_ one of them has BGP on their resume as a skill.

0% of them have correctly been able to explain what BGP is used for.

Junior candidates for what position?

Would answer "I use it host servers at home and have load-balanced access to internet via several end-users ISPs(no BGP sessions with ISPs so 2 VPN tunnels from home to server + 2 BGP sessions from home to said server via tunnels and server itself have session with it's ISP) count?" :)

Would "I'm just getting lists of IPs blocked by local censorship authority/IPs which are better to access via IP from OTHER country to put them all in VPN" count? :)

p.s. I'm not network admin and never put "BGP" on resume.
