That does not really mean much I am afraid. For exemple, Theranos, whose CEO and COO have been found
guilty of fraud after more than a decade with its promised product still not released, also showed their "progress" much in the same way as CIG hypes up SQ42 with the videos you linked:
Etc
Much like SQ42, pretty sure the Theranos research teams and labs were "working" on the Best Damned Blood Test System Ever.
Much like SQ42 though, the product was never released. In the case of SQ42, it is 10+ years and counting. For Theranos, their "work" also lasted over a decade to only end up with no real products, and its leadership sentenced for fraud.
So as you can see, short of getting SQ42 actually released, and especially given the outrageous delays by CIG so far, those videos you linked do not mean much.

Or this one from one of its formerly more ardent backers:
