I'm 100% that the future security-wise is stuff like esL4 (the L4 micro-kernel, but which has been formally verified to be free from a lot of common mistakes typically leading to security exploits).
So before criticizing things as "toys" because they have don't have goto etc. you have to realize that there are ends (security) that do justify quite some means.
And don't get me wrong: I've done my faire share of 680x0 and 80x86 assembly coding and just loved to be "in control" of everything. It gave me a sensation of power.
But now I much prefer to look far ahead and dream about the days where we'll be able to use provers on not just micro-kernels that are 7000 lines long (and already on such a trivial number of lines already find hundreds of potential security exploits which have all been fixed) but also use provers on much bigger programs.
So saying: "I want to be able to modify a lookup table by accessing two bytes as if they were a 16-bit word so that on the next pass I'll automagically JMP to this place" (I'm just making that up) is, IMHO, a bit shortsighted when considering the real problems we face today.
Most people have way enough power and totally underused computers (often with many cores idling). The problem is hardly CPU perfs.
I'm not trading security for performance.
