This is a good vid for those who want to attempt grasp logical deduction fundamentals to arrive at great conclusions. To shorten the time needed Ive pointed a three key places to begin, to get the overall gist of Constructor Theory as used by great scientists of past.
I skimmed a 2nd time, the Contructor Theory ---logical deduction starts at 10:15--- is the pathway ive used via my explorations of prime numbers, that, led to my four lines/levels, that, led to spiral-base, di-polar invagination to create our physical reality aka sine-wave patterning / \ / \.
After 10:15 he mentions logical deduction again at 11:13 --via David Deustch who I was communicating with back in 90's--- and to get the gist of this logical deduction it may be best to start at at minimum 8:20 with specific information set of entanglement of speculated quantum gravity or not.

3 prime structure via triangulation { 60 degree-ness } as any carpenter can attest to stabilizing a square/cubical residence, see 8 surface triangles of Vector Equilibrium aka cubo{6}-octa{8}hedron ergo 4 diametric axi,
4 systemicall transformative --- as seen with four axi above--, however, the systemically transformative only occurs with the 3 diametric axi of the 6 surface unstable squares { 90 degree-ness },
5 prime ----? cosmic meaning ?----
6 regular { 2D nucleated purity 120 degrees } circles/sphericals defined 6 regular triangles of convex hexagon, around an nuclear 7th regular circle/spherical,
7 prime, irregular irrational polygon 128.57 degrees whereas the other first nine convex polygons have whole rational angles
So in my 2D lattice above consisting of four lines/levels above we find linear sets of regular, nucleated convex hexagons. Once we curve each line around to meet itself we define four four kinds of great and semi-great circle planes of a torus. ( )( ) is a torodial bisection/cross-section ex seeing a cross-section of a dougnut from side-wise view, if laying on a counter.
A top view cross-section would like this ( O ) or as ( () )
