No. The holy grail of computing would be taking an instant snapshot as you do with emulators/vm's from anywhere, allowing you to rollback anytime, restoring the CPU and memory settings in the spot. With incremental snapshots, 'branches' and so on, switching back and forth seamlessly as you would do with save states under an emulator.

And with 'no time', with a delay of less than 5-10 seconds on creating/restoring a snapshot.

On search, as they stated, Recoll did it fine over 20 years.
