Please explain how your 10-times-as-accurate "solid state sensors" will determine airspeed--the salient part of that word being "air."

Airplane application of such a sensor would basically require a little metal peg or even simply piece of metal foil stuck on a wing. The principle of operation is such that you heat a piece of metal to a specific temperature and measure the amount of energy required to keep it at that temperature. The bigger air flow cools it faster so more energy is required to keep it at constant temperature. Damaging/disrupting/contaminating such a sensor is orders of magnitude less likely than Pitot tube.
Pitot tube is really an archaic sensor that is used in aviation (in my view) only because of historic and bureaucratic reasons. They continue to use it in spite of constant problems with it - ice and bugs clogging it and causing crashes.
To begin with, Pitot tube does not even measure directly any kind of flow but pressure difference. To calculate some sort of flow/speed out of it you need to know current air density.

On top of it all, the pressure difference measured by Pitot tube depends on angle of attack, which adds even more problems.
On the other hand, hot-wire mass flow sensor reading is directly what you need for better control of flying condition as it it the mass of the air flown around the wings that gives the lift. Or in other words - thinner air gives you smaller lift than thicker air at the same speed. Using this sensor in vacuum would give you zero flow reading and zero aerodynamic lift even if you were going at a very large speed.
Meaning, if this technology was known from the start, that's what would have been used - because it directly measures what is needed to maintain required aerodynamic lift.
Hot wire mass flow sensors are used in every car produced today. It is a well-known technology.
