So LEGO has a new set of electronic hardware (standards). They are apparently not compatible with the previous generations of Mindstorms. Of course, that may be adjusted with some *ahem* modifications. I'm thinking especially of the sensors.
I'm going to check out the Boost set (out for a couple of years), which is blutooth compatible, and it's interface plugs are compatible with the new Mindstorms Inventor/Spike (educational variant) which came out late last year (2020). Apparently there were roll-out problems due to the pandemic.
All of the new hardware seems to largely run off of applications from smart devices. Boost is apparently presented as a mostly remote control type of affair. However, someone in that community has found ways to expand the programming capabilities, and that made me think it was worth a look.
Though there is currently a limited sensor set, LEGO has combined functions into single sensors. One sensor is a combination touch (on/off button) and force-level (pressure) sensor. Another is a light/color and distance sensor (IIRC). These combos are both possible possibly wonderful and terrible. A sensor multi-plexer sure would be nice.
