Indeed, I've noticed this too. Classic Trek has computer being fiercely logical machines, with some ability to speculate but only based on a logical synthesis of data, and only in a deterministic and error-free way (barring physical/hardware problems or bad data of course). It actually seems quite artificially limited compared to what's happening now!
