The article I linked doesn't mention crypto or Bitcoin. It does illustrate a point though.
Tech companies, specifically computer hardware manufacturers, hold back technology they have already discovered specifically to make more money milking the ones they currently offer for everything they are worth.
Bitcoin has a problem... the problem is user access to affordable hardware technology that would allow it to scale. The same companies that have everything to gain from Bitcoin failing are the same companies Bitcoin needs to scale. It all comes down to greed. $$$$
Please consider this every time you speak about the scaling debate. It NEEDS to be mentioned more often. It is the sleeping giant X factor that we are not discussing because it's too "big picture" for people to realize when staring at lines of code and numbers all day.
