Except for C, Objective-C(++) and C++, all other programming languages, even systems programming ones do bounds checking.
And at least in C++, thanks to the STL or similar library there is the option to always enable bounds checking.
So even if the market didn't got hold of Algol, except for C and languages that offer copy-paste compatibility with it, all other ones do offer sane defaults in terms of security.
Ada, Eiffel, Java, C#, and Go are doing fine. All making money. :P Three even used in operating systems with two in embedded systems. So, can be fairly efficient, too.
Note: Not to mention Unisys still makes tons of money off their ALGOL machines from Burroughs. IBM & Fujitsu still service PL/1. So, old ones too.
