Most technologies go through an S shaped curve. Initial slow progress, then very rapid advancement, then slower progress as they hit various limit. After that there are incremental improvements, but not the huge changes seen before.
I think you are trying to compare a technology that is in the middle of the rapid advancement phase, semiconductors, with one that is in the top of the S incremental improvement phase.
Compare a London to Brighton run car from 1900 with a car from the 1970's. The 70's can go maybe five times faster, can travel thousands of miles without breaking down, compared with tens. A reasonably well off person could buy one, compared with only the super rich in 1900. In the last 40 years they have got more fuel efficient by perhaps a factor of two and the cost has come down by a factor of two or so. Reliability and service life by two or three times. Nothing like the change in the last 40 years compared with the first 70.
Similar thing for aeroplanes. 1904 they are made of wood and string and can go a few hundred yards. Sixty years latter jet passenger planes do 500mph across oceans. Fifty years after that they still do 500mph and look similar, but are several times cheaper to buy and run, so almost anyone can afford to fly.
