Fair point. A lot of people are find RNG distastful, and a lot of people also want skilled/involved/deeper exploration mechanics. Yet some other people are also suggesting dropping probes (as if that were somehow different than hitting a honk button, eg one-button-press mechanics). Personally I think the whole Probe idea makes the mistake of kicking the can down the road and only exchanges the honk button for a deploy-probe button. There is no added gameplay value from probes. The only cool thing added here would be a probe launching animation, and maybe a passive readout. Now if there was an active readout, were the player used the probe as a manual sensor, that would be something, but why take the extra time-sink step? Why not just use ship board sensors and ship-board readouts?
The only added-value gameplay reason I can see to add probes would be to send them places we couldn't or didn't want to go, like black holes/neutron star/white dwarfs, or superfast probes that could "semi-highwake" to distant stars within a system.
As for RNG, I think it will always be built into the game in some sense. I mean, every system is created in effect by RNG via the stellar forge. The question is, will the way we find things via RNG involve any human decision? For example, using sensors to zero in on high probability zones for finding useful materials. This could involve skill why using the sensors to sweep a surface, being able to ID visual terrain patterns and sensor based chemical signatures etc. However the actual specific location of items and the base distribution of elements and terrain/planet types within a system would still be RNG.
