Did first a linear fit, so in 2023 (assuming this is when
Ada2X will be), it shows there will be -0.23799 compiler
vendors.
I used 2.5 vendors for 2012, which is half the 5 vendors
you said there were in 2000.
In[19]:= data={{2000,5},{2012,2.5},{2017,1}};
f= Fit[data, {1,x}, x] (*linear fit*)
Out[20]= 465.759 -0.230349 x (*the line equation*)
f/.x->2023 (*see what happens at year 2023*)
Out[21]= -0.237991
-----------------
Using Quadratic fit, shows there will be -1.15588 compiler
vendors.
In[16]:= data={{2000,5},{2012,2.5},{2017,1}};
f= Fit[data, {1,x,x^2}, x]
Out[17]= -21276.4+21.425 x-0.00539216 x^2
f/.x->2023
Out[18]= -1.15588
Since it is not possible physically to have negative
compiler vendors, then using zero seems to make more
sense.
