it is a very hard task. To make advanced machineries high sensitive control and measurement systems are required.
private companies can't afford it unless they get serious government fundings. It's said in the tweet, 10 billion Euro. Almost same with 120 F-35.
And money can't solve...

no suprise why TEI's TS1400 engine cant work over 30,000 RPM yet. Turbine blades are not suitable for such performance.
