Space X Shares

My husband has long discussed buying shares in something and leaving them until we retire and he was mulling over Space X which launched today at £100.07 ($135) per share and when he asked me for my thoughts because i am into all things Space related, i replied that i would be more interested if Elon Musk wasn't involved because he is a complete dick.
Financial experts are saying that the shares are overpriced at £100.07 but on release they are expected to go up to as much as £141 driven by massive hype before settling down to what they consider it to be it's real price of around £47 per share.
I asked a Financial Agent who is on top of these things and he said to hold fire as Space X is tens of millions in debt and lost billions last year and are already billions down for this year already and did post a warning that  it 'may not achieve profitability in the future' so don't touch it.
Not that i disbelieved him but i asked Ai anyway and it came back with the pluses being it has massive growth potential with its Starlink satellite network and is the front-runner in modern commercial space exploration but the minuses are it is hugely in debt and the shares are hugely overpriced so pretty much what our guy said anyway.
I did buy some 'pretend shares' worth £1676 in January acting on Ai's suggestions to see if i trust it enough for next year and buying 'actual' shares and halfway through the year I am £466 up, which is nice.
