May be a 16kB base 10 mechanical general purpose computer was to much in 1833. However if he had kept the machine at 1-2Kb and had used binary for the main machine and a second machine purely for converting between binary and decimal.
Such a machine might have been doable in such times but in our history we had to wait for IBM.
So if this had been the case and the project had reached a success with people following on pretty quickly in that market we could be 50 years ahead of where we are now.
So we might have discovered transistors near the turn of the century. We might now be 60 - 100 * the density of components and have far more vertically orientated circuits all working off photonics by now.
As a result of being ahead in computing we might have better ways to fly and would almost certainly have better batteries.
So how important can the efficiency of a design choice be well it could put things forward decades or backwards a bit.
Not a lot of people realize this as they only want something to work efficiently for getting into the market they don't see the bigger picture so easily and failures lead to the clock being pushed backwards on some innovations.
