Went by and through (the only?) lengthy video of Genrich Altshuller (main author of TRIZ) on youtube:
Is it just me or from today’s perspective the performance is rather …questionable (not to say weak)? The only part which is both lively and not “pressing its own line in the most obvious way through other peoples opinions” is a part with no “other people” – the one with the bus on a street. That is strange – very unlike many available (public) impressions/reviews of Altshuller’s followers about his trainings.
