One of my favorite Engelbart sayings might relate to the "Mastodon is too confusing to learn" claim. Paraphrasing, he said that if ease of use was the ultimate aim for a tool, the bicycle would never have evolved beyond the tricycle. #technology
@hrheingold Yes, but lots of people still learn to ride a bicycle with training wheels or scooter bikes. The analogy is lacking a bit.

@luxzia @hrheingold funnily enough (forgive me if you already know this), training wheels are going out of fashion in favour of 'balance bikes' (frames w/out pedals)--turns out training wheels impede rather than enable the hard parts, balancing/steering, instead emphasizing the exact wrong thing (the pedals).

this seems relevant to howard's quote, i think?
