The main point of the video was that IF this was a factor, then the problem is MUCH MUCH bigger for boeing than just MCAS.
Thoughts?

After take off, if the AFDS has "captured the lower MCP attitude" you may still be in "take off thrust" so the aircraft will not transition to "climb thrust". Selecting a pitch mode (VNAV/FLCH as Boeing recommends FLCH) will bring the aircraft into "climb thrust". Unless the crew check's the A/T and pitch FMA's to ensure climb thrust is set, then the aircraft starts to increase speed to approximately 240 knots below 10,000 feet. VNAV will honor flap placard speeds minus 5 knots.
