"When will the tech industry stop coming up with shit ideas such as keyless cars that are just security disasters waiting to happen that are built on fundamental designs and software from the 1960s/70s"
Absolutely agree. However, secure and correct computing and architectures have been around since the early 1960s. Just look at B5000 (now Unisys MCP machines). But scientific computing where every cycle matters rather than security won out.
It is time to separate these two needs. Faster performance comes from faster electronics, not by ignoring fundamental issues because they cost processor cycles.
