Modern mines have programmable target discriminators that use multiple sensor modalities in addition to a programmable self-destruct. A cow or a goat herder usually won't set these off.

Many types of sophisticated mines cannot be trivially cleared with line charges or engineering vehicles. Soviet style mines can be cleared this way but aren't the only kind that exist.

This tech isn't sophisticated but it costs money and requires maintenance. Many militaries don't use them because they want weapons that can sit in a warehouse for 50 years with zero maintenance.

The military purpose of mines is not to kill anyone. It is to deny use of space in order to shape the battlefield and trap the adversary in areas where they are exposed to other weapons. Mines are highly effective at this purpose and will be for the foreseeable future against almost all adversaries. This is not controversial.

The "expert" in the linked article has no background in mine warfare, only EOD. This became obvious when I was reading the article because it presented an unexpectedly naive understanding of mine warfare. That perspective might make sense if your only experience is clearing old Soviet mines and IEDs but it doesn't generalize.
